10.6.6 on Hackintosh

January 9, 2011 12 comments

Mac OS 10.6.6 has been out for a couple of days now, and I have successfully updated my main hackintosh to this release. The previous 10.6.5 release had required the addition of “pmVersion=21” to the kernel flags section of my com.apple.Boot.plist file, but this latest update required no further modifications.

I haven’t found any problems with this release on my hardware. System updates always take a little longer on my hardware since I make a full bootable (and tested) backup before every major change, but that’s a good idea on Apple hardware as well since problems after updates are not unheard of.

iOS 4.2.1 Jailbreak released

November 23, 2010 Leave a comment

New Firmware, New Jailbreak. Following yesterday’s release of iOS 4.2.1, redsn0w 0.9.6b4 is now available to jailbreak it. There are some conditions attached, so best read the post at the iPhone Dev Team Blog before attempting the jailbreak.

Another thing to remember is that this is still beta software, so may not work as expected. I followed the instructions the app gives to enter DFU mode, but found redsn0w stopped at the waiting for reboot screen. I got around this problem by putting my iPhone 3GS into DFU mode manually before running redsn0w, then pressing the power button when redsn0w stopped at waiting for reboot.

Once Jailbroken, there are a few more issues. SB settings isn’t currently working for me, and crashes springboard when I try to use it. No doubt this will be quickly fixed, but for now just remember this is new software, so either wait for the jailbreak ecosystem to catch up or enjoy the ride.

Update 25th November – Cydia updated SBsettings Toggles today, and SBsettings is now working perfectly with 4.2.1 on my 3GS.

10.6.5 on Hackintosh

November 13, 2010 14 comments

Mac OS X 10.6.5 is out, and I have sucessfully installed the update on my main hackintosh with one minor change to my com.apple.Boot.plist. To recap, the important hardware in this hackintosh comprises:

  • Gigabyte Ga-P35-DS3R motherboard
  • Intel Core 2 Quad Q6600 processor
  • 4Gb 667 Mhz DDR2 SDRam
  • Nvidia GeForce 9800GT video card

The 10.6.5 update includes a new Kernel (Darwin 10.5.0) which doesn’t match the current custom SleepEnabler.kext, so will cause a kernel panic during startup. This is easily fixed, as SleepEnabler.kext can be passed an instruction through the com.apple.Boot.plist Kernel Flags section to set its declared version to match the kernel. Here’s my com.apple.Boot.plist from /Extra with the added instruction in red. Read more…

iPad iOS 4.2 new features

November 10, 2010 1 comment

iOS 4.2 is due any time now for the family of iOS devices, and the GM (Gold Master) for iPhone, iPod and iPad is available now from several places for those who want to try it. The iTunes 10.1 beta is required to activate and sync with a device running 4.2. I found both at gumballtech, and have been running the Mac version of iTunes 10.1 beta and iOS 4.2 on my iPad for the past week. The features introduced with iOS 4 for iPhone are now available on the iPad, and it’s doubled the amount of tasks I do on the iPad. Presented here are some screenshots and details of the new features I have used. This is certainly not a complete list of new features, so if you you have any requests for more information leave a comment.

Multitasking
Just as with the iPhone, the addition of multitasking to the iPad makes it a joy to use. Tapping a link in the Mail application takes you straight to Safari to open the link, then a double press of the home button and a tap of the Mail icon takes you back to where you were in Mail. Being able to quickly jump between apps makes iOS 4.2 much faster to navigate. Read more…

iOS 4.0.1 and iPad 3.2.1 released

July 15, 2010 1 comment

Software updates for the iPad and devices running iOS 4 are now available through iTunes.  iPad OS 3.2.1 includes fixes for Wi-Fi, handling of PDFs in Mail and video playback, as well as adding Bing to Safari’s search options. iOS 4.0.1 for iPhone 4, 3GS and 3G lists an improvement to the formula used to calculate the signal strength bars as the only change.

I’ve just updated my 32Gb WiFi only iPad to 3.2.1, losing the Spirit jailbreak. I’ve found the benefits of a jailbroken iPad to be limited so far, so intend to wait a few months for the bugs to be ironed out of existing jailbroken apps.

Jailbreaking a 3GS with iOS4

June 23, 2010 Leave a comment

With the iPhone Dev Team’s release of PwnageTool 4 yesterday (and the 4.01 update today) I was ready to jailbreak my iPhone 3GS. It’s been running the iOS4 beta 4/Gold Master since that was leaked, but being on iOS4 already had prevented the use of the beta jailbreaks available before the public release of iOS4. There were still several steps involved to achieve the jailbreak, as stipulated in this condition from the Dev Team’s blog:

If you have a Jailbroken iPhone 3GS with the OLD BOOTROM and you DID NOT use Spirit to jailbreak then you can create the ipsw with PwnageTool 4.0 and restore with your jailbroken recovery mode

My 3GS uses the old bootrom, so OK there. The requirement for a jailbroken 3GS NOT using Spirit meant the first step was to downgrade the firmware to 3.1.2. That’s an easy step if Cydia has your SHSH stored for the previous firmware, as mine are.

The next step was to jailbreak the 3.1.2 install using redsn0w 0.9.2. Once this was confirmed to be working correctly (just look for Cydia to be installed) PwnageTool 4.01 was used to produce a custom iOS4 ipsw. The iPhone was then put into DFU mode, and iTunes used to pick the custom ipsw to restore.

Both times I restored a firmware during this process a 1015 error was given after the restore. By that time the restore had successfully completed but the iPhone was stuck in recovery mode. The freeware RecBoot utility was used to get out of recovery mode and back to normal startup.

A backup had been made by iTunes before starting the jailbreak, so this was restored once the jailbreak was completed. I now have SBsettings back on my iPhone, giving fast access to 3G and WiFi on/off to help conserve batter power. There’s a few other useful jailbroken apps that haven’t been updated for iOS4 compatibility yet, but hopefully that will be done soon.

Once again thanks to the iPhone Dev Team for redsn0w and PwnageTool, and to Saurik for Cydia and enabling the downgrade to earlier firmware.

10.6.4 tested on hackintosh

June 17, 2010 3 comments

My original hackintosh has now been updated to 10.6.4, and as was the case with the past few updates a new version of sleepenabler.kext was required to prevent a kernel panic during boot. The 10.6.4 sleep enabler is available from Insanelymac.

The Snow Leopard Mail application has received an update to version 4.3, showing the above dialogue when first launched. The upgrading of mail messages took only a few seconds, unfortunately it was followed by this warning.

Letterbox is a Mail plugin that adds a widescreen view with the message preview pane on the right of the window. Fortunately developer Aaron Harnly already has an update to Letterbox 0.24b7 which is compatible with 10.6.4.
