sot_22 Posted November 3, 2014 Author Share Posted November 3, 2014 Yosemite report alright i installed Yosemite yesterday and at first i thought it was slow with lame colors... but after some reboots and playing with it now seems faster and smoother than Mavericks , particulary the launchpad animations which on Mavericks on my external monitor 1680x1050 (with display port to dvi cable) was laggy with the screen full of icons, now the animation from page to page is butter smooth to my surprise ... they improved the gfx drivers for sure. now the buggy stuff , Yosemite seems to be a little more cpu hungry and has a lot of bugs that shows everywhere if you look on details but its not groundbreaking and with updates i hope apple will make it more rigid experience, like some services not responding - some apps doesn't close completely - some gfx glitches on upper bar, there are some errors in console which doesn't seem to do anything but slow down the system and it appears they are on real macs too, like : kernel[0]: BUG in process suhelperd[283]: over-released legacy external boost assertions (1 total, 1 external, 0 legacy-external)com.apple.xpc.launchd[1]: (com.apple.imfoundation.IMRemoteURLConnectionAgent) The _DirtyJetsamMemoryLimit key is not available on this platform.com.apple.xpc.launchd[1]: (com.apple.appkit.xpc.sandboxedServiceRunner) The JoinExistingSession key is only available to Application services.com.apple.xpc.launchd[1]: (com.apple.DataDetectorsDynamicData) The JoinExistingSession key is only available to Application services.com.apple.xpc.launchd[1]: (com.apple.FileSyncAgent.PHD.isRunning) The HideUntilCheckIn property is an architectural performance issue.

[ps. i saw some errors?! on booting Yosemite usb installer about something i don't remember but they didn't seem to affect anything] The first thing i did was to remove all widgets from notifications , reduce transparency and disable opening folders animations with TinkerTool and make Appearance for buttons menus etc Graphite , now it seems like a proper OS ( ... ) so in all i like it for now and expect to be better in the future .

FluffyLlama Posted February 12, 2015 Share Posted February 12, 2015 This pack has helped me tons, and I now have a nearly perfect X220 running Yosemite! Sleep/PM/Graphics/Sound/wireless (AR9280) are all working perfectly. Clover bootloader, I might add. The only issue I'm having so far is Ultranav: Everything works perfectly, but as I hate using the touchpad I've disabled it in the bios - but when I do that, middle mouse button scrolling stops working and VoodooPS2Trackpad gives a console error at boot [identify Touchpad command returns incorrect byte 2 (of 3): 0x00]. Has anyone put together a different version of VoodooPS2 that allows me to disable the trackpad in OSX (or set it to scrolling only), or is there a plist to control that?

sot_22 Posted February 13, 2015 Author Share Posted February 13, 2015 hi and thanks for confirming that the pack/dsdt works you don't need to disable trackpad from bios , enable it and just change the options on mac system preferences -> trackpad , you can disable what you want there and only use it for scrolling, update : sorry man since all is working so well and i use mostly my desktop setup lately i tend to forget! dont do anything there is a shortcut to disable the touchpad , just press option + PrtSc (the option key is the windows key on my setup) this disables the touchpad and leaves the trackpoint with buttons working , just press it again and it enables the trackpad. (i used this a lot cause touchpad sometimes disabled itself and i thought that voodoops2trackpad crashed or something but if i press the combination above it worked again so this is the best solution) Link to comment Share on other sites More sharing options...

McDonnellTech Posted March 18, 2015 Share Posted March 18, 2015 I tried to use what I discovered in this thread and on a few others sites to put together a concise guide to installing OS X 10.10 Yosemite on the ThinkPad x220: http://x220.mcdonnelltech.com/ Links to all of the necessary kexts and utilities are in the guide. Hope this helps. There's a feedback form at the bottom of the guide if you find anything that isn't accurate. 1 Link to comment Share on other sites More sharing options...
