Mac OS 10.5.6 thwarts jailbreakersMy colleague David Morgenstern yesterday blogged about some of the changes in the freshly released Mac OS 10.5.6 update. The operating system update (release notes) has over 40 fixes and includes improvements to AirPort, MobileMe, Time Machine, Safari and better gaming performance.

Unfortunately, it has also unleashed its share of headaches.

iPhone Alley notes that 10.5.6 prevents a Mac from recognizing an iPhone in DFU (Device Firmware Upgrade) mode. DFU mode bypasses the current OS installed and allows you to upgrade or downgrade your OS. This makes it impossible to jailbreak and/or unlock an iPhone using PwnageTool or QuickPwn.

I recommend waiting at least 72 hours before installing any update to the Mac OS, even longer on a production machine that you use to make a living. It's best to wait several days and read the troubleshooting sites and the Mac OS X Leopard thread on Apple's discussion forums before diving in. After you feel comfortable that all the bugs have been worked out, make a bootable backup of your system (and test it!) before pressing the install button.

Have you installed 10.5.6 yet? Any problems?

Update: The Energy Saver presets previously available under the battery icon in the menubar seem to have been removed in Mac OS X 10.5.6 (picture).

Update 2: Macworld's Rib Griffiths took notes that Apple apparently updated various Bluetooth software components, Migration Assistant got some polish, and the Podcast Capture app was updated to version 1.0.3. Other low-level drivers, frameworks, and extensions were also updated, and even the Apache Web Server manual got some attention.

Update 3: New threads in Apple's discussion boards complain about everything from broken AirPort, support for specific Bluetooth devices getting removed, and choking installations (TUAW).

  • Installed all is fine

    I can't tell yet if it resolved my #1 headache of having the wireless connection dropped.

    EDIT: Nope didn't fix my connection from suddenly dropping. It's just click the icon shut it off and back on, but what a hassle for the irregular users of the machine who I have to teach that too.

    I disagree with Apple forcing purchasers of the I-Phone to remain on AT&T's network in this fashion, provided that the owners of said I-Phones have completed or bought out their required service contracts, or otherwise satisfied the CONTRACTUAL obligations required in order for AT&T to subsidize the purchase price of the phones, those users should be able to switch networks (and I think there is legal precedent) without interference from Apple.

    {And, no, just because AT&T based their price of the phone on the assumption of permanent AT&T subscription, that does not equate to a contractual obligation on the part of the subscriber. If the subsidy is based on a 2 year contract, with an early buy out clause, then completing the contract period or paying the buy out suffices.}

    But, once again, Apple plays by their own anti-competitive, monopolistic, hypocritical rules.

      medezark, if you remember, Apple and AT&T signed a 5 year
      agreement. Apple must enforce the use a their network as
      AT&T can't. Personally I can't wait for the 5 year contract
      expires.

    • You're getting jailbreaking confused with unlocking

      Jailbreaking does not equal unlocking, so you can disagree with Apple keeping the iPhone locked all you like, but this story is about a different issue.

      This is regardless of the fact that in the U.S. there's only one 3G network that uses the HSDPA frequencies that the iPhone runs on, anyway. So the only reason for U.S. customers to have an unlocked iPhone is to use SIM cards from other carriers when out of the country. That is, unless you want to be limited to EDGE connections when using an iPhone on T-Mobile's U.S. network. (It's not Apple's fault that Verizon, Sprint, and T-Mobile don't use the same 3G technology or frequencies as the rest of the world.)

  • Brilliant article...

    Delay upgrading your Mac firmware for legit security issues because it may break you "jailbreaked" iPhone. If someone is hacking their iPhone to this degree, I seriously doubt they need the latest and greatest security patch from Apple.

    • You miss it

      This sounds like a serious post from you, Mike. So I shall try to set the record straight. The problem isn't that a Mac user with a jailbroken iPhone can't sync it, it's that the inability to go into DFU mode prevents you from jailbreaking in the first place. Therefore, anyone considering jailbreaking should do so before updating, or they should do it in Bootcamp.

    • Apple might be breaking the law

      If they are doing this disallowing a iPhone in DFU mode from connecting to the machine, since jailbreaking is a legitimate, LAW-PROTECTED thing in the United States and many other countries.

      • There is no law

        There's no law saying you can't do it, IF YOU CAN DO IT.

        Similarly, however, there is no law saying they can't do what they like to prevent you from doing it in the first place.

        There's a difference betwen a law that protects you from being prosecuted for doing something with a product you own, and a law that says a company must not prevent you from doing things with its products that it doesn't authorize. If that were the case, DRM wouldn't be legal (not saying that I support DRM, just that legally companies have the right to use it if they so choose).

  • RE: Mac OS 10.5.6 thwarts jailbreakers

    I always manually software update my mac. However, it was the longest software update I have ever experienced. I was very tempted to restart the machine a few times butI left it alone. I ended up deleting my preference file for the first time since owning the machine and that took alot of time also. Honestly, I can't tell if the update and/or deletion of preferences improved the overall snappiness of my 1st gen intel imac. Anyhoo, good luck all.

  • RE: Mac OS 10.5.6 thwarts jailbreakers

    I have experienced no serious problems with 10.5.6 on my MacBook Pro. However I heard issues with Mail but I don't use that as my mail client so that one of the few apps I can't tell if there is an issue. I did noticed an increase of memory and swap as others have observed.
    Also I don't have any iPhone to test the thwarting jail broken iPhones.

  • DFU mode is a legitimate last resort restore mode isn't it?

    [B]If a restore using Recovery Mode doesn't work you will want to use DFU Mode as a last resort.[/B]

    Guess that won't work anymore. What the heck, just go buy a new one if Recover Mode doesn't work.

  • The 80/20 rule applies

    If you're part of the (likely) vast majority of Mac users, just using it as a PC-that-works-better, then the 10.5.6 update is largely a non-issue. Nothing has broken for me in 20+ hours of use. Nothing I use regularly seems negatively affected. There have been a couple of serendipitous positive effects; Safari 3.2.1 crashes less often now (3.2.0 was rock-solid; Apple, how can I downgrade?) and for some silly reason, NetBeans loads noticeably faster (nearly 2 seconds faster...why? Xcode doesn't.)

    I blogged about early impressions of the update and about how I felt about Mac updates in general (as a longtime Windows and Linux guy) at http://archlever.blogspot.com/2008/12/happy-updating.html
