Snow Leopard install fails? Find a flashlight!

By | September 3, 2009, 2:42pm PDT

Several users report a blank screen after installing Mac OS X 10.6, Snow Leopard. However, one suggested fix is to find a flashlight to read the screen.

In the Apple Discussions topic Display blank 24hrs after SL install, as with another describing a “very faint screen,” MacBook Pro users report that the backlight just goes out during the installation.

Some posters suggest that the display went to sleep during the installation and then it didn’t “wake up” with the necessary brightness for humans to see the screen.

One answer is to find a flashlight.

I had a similar issue on my MacBook Pro. I was able to complete the installation by using a flashlight on the screen. My problem was that the screen was very very dim that it looked blank. I also attempted to increase the brightness of the display, but that didn’t work. Once I used the flashlight I was able to select my language and locate the mouse so I could select accept. The installation completed once that was done.

In addition, you can try increasing the brightness. F2 is the usual keyboard command for increasing brightness. Depending on your config, you may have to hold down the Fn key to get this Function key to work.

Another post points to the Energy Saver settings as the culprit:

My installation was on a MacBook Pro Core 2 Duo. After I finally completed the installation, I had to change the screen brightness setting and manually change the gamma in the calibration of the display to 2.2. I now picture the Snow Leopard holding a high-end flashlight in its mouth.

It is possible that this problem could have been avoided if the display preferences in Energy Saver had been set, before the installation began, to never have the display sleep. My display went dark and did not recover after about the same amount of time for which sleep was set.

So, if you’re heading into an install of Snow Leopard, it might be best to manually turn all of the display sleep settings to Never (and maybe do the same for system sleep as well as unchecking the hard disk sleep box). Of course, it’s never wise to install systemware when running on battery power. But anything can happen, or the installer may decide you’re running on the Power Adapter settings.

304 Macs, and never had this happen to me.

I have to agree, I installed Snow Leopard, on all my
home machines (4) and an entire lab at my school (~300),
and never had this happen once. Did this person attempt
to use the function key?

I think you are absolutely correct. I am a Mac, PC, and Linux user. The main goal of having closed hardware is to ensure everything works. There is no excuse for someone not catching this before it went out the door. I have seen Windows not finish installs blue screen after install, and etc BUT I know that is generally an incompatibility in my configuration. This OS only works on intel. How large can the test be be?

I really like my Macs and have never had issues in the two years I have been a convert. But in this case, someone needs to lose their Job.

Mac users ...
BryEDS@... 4th Sep 2009
This isn't a surprise at all; I've seen just as many problems on mac systems as I have in windows systems over the years; they are NO bettr in any way than a windows system! I've seen users lose ALL of their files due to installing the latest updates, hard drives fail just as often, and most users on the mac systems never delve into the system preferences or try to tweak their system, so they live in the false belief that it is a more simple system; because there's only one button! HA! Where's the mac users ranting and raving on about how terrible the OS is because of this error? Oh, no, they live up to their reputation and defend their beloved precious by being quiet and not replying ... Macs are great, if you wish to live by the way of the mac os, the mac software, and everything mac ... it isn't that great! Enjoy your macs, your constant updates, your need to enter a password on the system to install something, even if there is no password, the constant prompts to enter your password to do nearly anything on the machine .... oh, wait, that sounds alot like Vista and the UAC feature they added ... WOW .... but its all denied and kept quiet! Mac users ... sheesh ...

It updates as often as my Vista box except it doesn't do it automatically, needs password authentication from secure sources and requires a restart for virtually every one of them.

I mean a restart for a web browser? WTF?

...be surprised at all. Then-again, I use mostly windows and only recently became a Mac guy after buying a Macbook pro.

There's a bug in snow leopard? I'm not surprised, it's software. As a programmer, I'm fully aware that anything as big as an OS installer is going to have a bug in it somewhere.

I find it fully possible that this problem did not occur in any of the test installs they did, and so they were unaware of the potential problem. You can't really expect any more from the developers, except perhaps fixing the issue in the next release.

Configurations.
Bozzer 6th Sep 2009
How many configurations does Apple need to test compared to Windows?

Come now, Apple is supposed to be a closed system and this kind of thing should be easily picked up via testing. But hey, Apple don't allow the average Joe to trial a beta of their OS...

Yes, you can expect more from the developers, you should never be satisfied with sloppy testing, which is what this amounts to.

It's a minor bug that is an inconvenience to people. It could be more serious if people panic and think the update broke their computer or monitor. Not a major issue, but it does make the company look sloppy.

We wouldn't post because we'd not bother to read the story. If I read
EVERY story about a flaw in Windows I'd never get anything done.

Now I do read a few, because I support clients who DO have Windows,
and I even have a box here running Windows 7 (and it's working fine
thanks). But seriously, why do you care?

I get it, you use Windows, and you like it - great. I've been "kicking
the tires" of Windows 7 and you know what? It isn't half bad. I still like
Mac OS X more, but I've got lots of Mac software, and I use the Mac
more (so it feels more natural) but I can see why you like it.

But you're only doing what you accuse "Mac-heads" of doing.
Honestly, most Mac users don't care about Windows - they're happy
with their machines, they don't read or comment on PC stories. OK,
you got a PC and you like it - I get it, really I GET IT, what the heck
has this got to do with the PC?

I agree with you, but...
FanaticGeek 7th Sep 2009
"But seriously, why do you care?"

Beacaus Apple fanboys are blind and full of
illusions about Windows (I, Linux user who
tries to convince everyone to use what I
believe to be a "superior" system rarely had
any problems on Windows) , because "Mac is so
perfect", because they can't say anything
positive about Windows nor anything negative
about Mac OS X, and because we're tired...

I use Linux, Windows and Mac. Yes, all tree are
good OSs and a lot of work has been put to make
them, all three have their qualities and flaws.

I'm satisfied with none, but I respect them
all. Now I'm a Linux fan, but when my brother's
computer has a bug (he installed Linux on my
recommendation) I tell him I'm sorry, and I
don't start blaming some one else or changing
the subject (eg. "Well, it would be worse with
Windows"). Now Linux (ubuntu in that case) is
free, is running in a cheap computer.

I'd like to buy myself a Windows or Mac box,
but i'm not paying extra if it has the same
bugs as my free OS (regardless of any open-
source ideology or the such).

However, I'm sure I would have dropped/I'd drop
any Linux distro if it had a similar bug before
it was even fully installed. What about with a
costly OS? Would I make an exception?

I'd like it if we didn't see stories like this
(and seriously, its trivial), but that's not
going to change untill iFans calm down and
accept Mac OS X as a normal OS with normal
problems and stop ranting and snobbing "PC"s.
(That goes for Linux fans too, to a lesser
extent)

Cuts both ways.
rahbm 9th Sep 2009
For whatever reason, ZDNet blogs are chock-full of Windows fanboys
(more accurately called bigots, shills and trolls) who lie awake at night
salivating at the prospect of being able to post an anti-Apple or anti-
Linux rant the following day. Either they are being paid by MS to do this,
or they really need to chill and get a life.

Yes, the Linux and Mac fanboys are tedious, but for some reason are not
nearly as numerous, or as shrill, and the Windows sycophants.

Back on topic: how many people have experienced this and what
suggestions do you have as a workaround?

All Bull#$%t
Appreciate-Tech 21st Sep 2009
First, if you got a "blue screen" you were not following the instructions
correctly in the first place and you installed your system complete with
incompatible 3rd parry plug-ins. Here is one of the most problem free
methods of installing install Snow Leopard problem free. First BACK UP
YOUR DRIVE using time machine and an external hard drive. On
completion insert the original disc which was supplied with your
computer. Select Install and erase of your hard drive. OS X will
completely erase your Macintosh Hard Drive and replace it with the
original system supplied with the machine. Use the second disk to
install iLife or any other bundled software. The run "System Update"
which will patch the system with every revision and security parches for
your specific Macintosh. When you have a clean 10.5.0 System and
system profiler reports that you are up-to-date. Insert the Snow
Leopard DVD and install the update as a custom update, select "rosetta"
as part of your update to cover applications not written in the Mac
native Cocoa programing language. Immediately there after you will
receive a few more incremental updates for both the OS and installed
Apple productivity (iLife & iWork) software bring your system version to
10.6.1. Restart the system with 6+4 keys held down and the system
will boot in 64 bit and stable. Then you can use Migration Assistant to
bring back your specific files and documents from your Time Machine
Back-up. It is thereafter suggested that you review the web sites of
your favorite plug-in's and 3rd party applications and you will witness
the most stable 64 bit OS you can run on Intel chips. For those who
just have to have the Windows PC "cool aid" experience, use Boot Camp
or VMware and install you favorite version of PC or LINUX OS and enjoy
two computers for the price of one! I run several versions of LINUX,
WINDOWS XP, VISTA and 7 as part of my application development
environment daily on a Apple Macintosh 17 MacBook Pro 3.06GHz Intel
Core 2 Duo, 8GB 1066MHz DDR3 SDRAM - 2X4GB and a 500GB Serial
ATA Drive @ 7200 rpm. This is the fastest machine on which you can
run ALL current versions of popular OS out of the box. This is a
capability often missed by the Zelots for Windows/Intel product.
Everyone wants a cheep machine, but have you ever considered that
with a MacBook Pro you can have as many machines as you want
running on this single platform, so what is rely at the root of the
complaints against the Mac, is it just the OS or the Price? Everyone gets
to chose what they can afford with no question we don't have to vilify
each other if we chose a different computing platform, after all I chose
a different car and wife from the one others did, we do not have to
chose the same. So cut the Bull#$%t and get on with the task you
purchased your choice of computer for and quit this pointless debate.
I had this issue happen one time on an old machine running
Tiger a long time ago... it locked down with the backlight off
, and was very hard to see until I could get fully logged in
and turn the brightness up...
My Mac-book went to sleep so i ewbooted and started over after turning the sleep mode to never, Worked great!

A temporary fix like that is OK, but does indicate

I thought Macs were supposed to be stable, easy, reliable, compared to Windows. At least, that's what Apple keeps telling us.

Guess I was wrong...

As others pointed out, if this would occur during upgrades from Vista to 7, the entire world would attack Microsoft and ruin it so that none of it will be left.

Honestly, this really looks like a big joke, like something from an Alpha release.

Try a Win7 Install
mswift@... 4th Sep 2009
I've done over 100 Win7 installs testing our proprietary software. It is eerie. You start the install, answer a few questions, and then go away and when you come back everything works.

It is very nice, the user vibe is very close to the current Mac interface (I have not played with Snow Leopard). The Mac feel plus unlimited applications, what's not to like?

Not to like?
ewelch 4th Sep 2009
Sorry, but only a Windows user could confuse the WIn 7 interface with
OS X of any flavor. I've got Win7 on order, and I've used the beta. Not
even close. And even more difference in terms of functionality. And
Windows users simply don't understand that because they've never
taken the time to get to know the real OS X. They just think it's
Windows with different eye candy. But it's not.

Applescript, Automator, Services, all the UNIX underpinnings. Etc.

Yes, Windows 7 is a great OS. It looks good. BUt your last statement is
the most clue-impaired of all. My Mac can run all your "unlimited"
applications, plus thousands that only run on Macs. Plus all the UNIX
and Linux stuff that runs in XWindows and doesn't run on PCs.

jeremychappell 4th Sep 2009
The Mac is really unlike Windows, the whole OS has a very different
"feel". Services on the Mac (well actually they're off NeXTSTEP - but who's
counting?) aren't like PC services (they just mean totally different things).
Mind you even amongst Mac users services are pretty neglected - Snow
Leopard has changed the UI for these to try and address this (they are
really useful, once you find them!)

I think most OS technology we use today (both Mac and PC) is a lot older
than 10 years!

100 Win7 Installs w/o a BSOD? Never!
i2fun@... Updated - 4th Sep 2009
Unless you are installing on newest hardware and every system is exactly the same, you could never get a 100 clean installs of Win 7ista or any other OS, except possibly a Mac with OS-X! ...just not this version.

The reason is simple. It's why Apple locks their OS to their own Hardware. But that's exactly why, as small as the number of people experiencing this, heads should roll on Software gone Gold and being distributed!

BTW... I've done over 20 Win7 installs on various old and new hardware, and I'm running a 20 to 30% fail rate. BUT.... that's expected with a new system that can be installed (or attempted) on so many different hardware layouts. But even that, doesn't even come close to what Linux is capable of being installed on. Which ranges from Cell Phones to the very largest hybrid chipped super computers.

IBM Roadrunner is the leader of the Linux Pack of OS Wolves at 1.8 PFLOPS. Try that with your Win 7ista or Apple Mac Snow Leopards! grin

Oh... and in case you haven't heard, IBM's Power7 chip can run Virtually any OS on this new chip. That can also throw down a gauntlet of onboard edram memory starting at 32MB+ (not even Intel has this)! ...me thinks the speed and power crown will be getting dusty in Big Blue's headquarters for years to come! wink

jeremychappell 4th Sep 2009
Wow, 100 installs?! I've only installed this on two systems, both worked
flawlessly - but they were both VERY new. So no problems even on older
hardware?

I really liked the Windows 7 installer - it asks all the questions up front
then you can just leave it, much nicer than the older XP install (which was
very chatty). Never installed Vista, so I have no idea what that's like.

four Snow Leopard installs!

4 our o4 perfect installs so far. Number 5 tomorrow.
That's about how easy installing a Service Pack is on Windows as well.

I just did a Snow Leopard install today on my moms iMac, went very smooth with a few button presses.

But when I upgrade a service pack on Windows, it's EXACTLY the same.

The first thing I noticed after installing Snow Leopard, was that once booted back in, you didn't know you actually installed anything. I think the only difference was a few more stars on that purple background.

I'm sorry, but THAT is a service pack.

Windows 7 is a much heavier OS upgrade, and yet a clean install is extremely simple.

Yea, that was me 15 months ago. I'm now back on PC hardware and running Windows 7.

Mac OS X is a great OS. Mac Hardware is good quality and well built. Windows 7 is a great OS and some PC hardware is good quailty and well built, too. So, for the same price that I sold my iMac 24" after a year's use, I now have a much more powerful machine with a better screen and equal quality and build. Each to his own, but even when the grass looks greener (Apple is a fantastic marketing machine) on the other side, the reality is that the grass was already pretty green where I was.

Windows REQUIRES the extra horsepower to begin with, for little effect.

My electric bills have gone down since moving to the Mac.

There is no way a 2.93GHz dual-core iMac with 7200RPM hard drive, 4GB RAM, GTX120 with 256MB RAM should load in 20 seconds while a Quad-core 3.60GHz Q9650 processor (400MHz FSB overclocked making it 3.6) with 10000RPM hard drive and GTX260/896MB RAM load in 90 seconds.

OS X's UI is more responsive compared to Vista (or XP), app loading is a heckuva lot faster... The only thing I never did was get a stopwatch and manually time how long it takes to do photoshop and aftereffects renders. With everything else I've seen, that's a waste of time.

The screen in my iMac is an 8-bit H-IPS. Excellent color range and shadow detail. I hope you are not referring to a 6-bit TN panel, because you would be flat-out WRONG in your claim.

But you like Windows. Have fun with Nefariously Fragementable Trashy Slush (NTFS), the registry, and everything else. I left Windows after years' (approaching two decades) of those and other issues. Microsoft puts out dilettante tripe. They have the marketing machine since they're not out of business, like how any company putting out such amateurish slop COULD stay in business. Then again, oligarchies have a vested interest to keep or elevate their status. Fair play is an alien concept to them.

One of the strengths and weakneses of the PC world is you have lots of choices, even crappy Lenovo 22 inch monitors that are unreadable if not in native resolution.

The less ram, the quicker the boot

Windows or Mac, this was true 10 years ago and is still true today - the
more ram, the longer the load time.

And now you know it's your low-end specs that make your machine load
quickly... Good to know that Windows 7 is actually functional with such a
tiny amount of ram, just like Leopard and Tiger, etc.
