LoBlanc Posted October 26, 2012 Share Posted October 26, 2012 I understand the idea here is to find out the real cause of the malfunction. But in the meanwhile for those who want a fully operational system I recomend to install the AppleRTC.kext from SnowL. Fully operational on my venerated P35-DS3R (ML 10.8.2, chamaleon installed in a separated partition as I have done many times following former suggestions from BlackosX -my greetings Sir-).

Using the patched kext should just work fine Never met with obstacles 1 Link to comment Share on other sites More sharing options...
LoBlanc Posted October 26, 2012 Share Posted October 26, 2012 Didn't work for me. I had it sometime under investigation but I did not get it really (elegantly) working with the RTC patched version. Perhaps I had other dependencies, since a.o. i tried different dsdt's... Link to comment Share on other sites More sharing options...

piratx Posted April 6, 2013 Share Posted April 6, 2013 (edited) Let's see if that fix my sleep/wake problem on Asus P5QC too.

mugatuboochu Posted April 30, 2013 Share Posted April 30, 2013 Could this be why after installing Mountain Lion on my laptop with Windows 7 Dual Boot that my clock keeps resetting and doesn't save when logging back into Windows? Do I need to apply this cmos reset fix? Link to comment Share on other sites More sharing options...

Do I need to apply this cmos reset fix? Yes, that's probably it. I have the same problem. Link to comment Share on other sites More sharing options...
jamiethemorris Posted June 30, 2013 Share Posted June 30, 2013 The clock thing is something different. Windows uses a different method for getting the time. Here is how to fix that: http://prasys.info/2010/01/fixing-time-sync-issue-with-osxwindows/ Link to comment Share on other sites More sharing options...
ApexDE Posted October 6, 2013 Share Posted October 6, 2013 Anyone has experience with AppleRTC.kext and OS X Mavericks? Does it still cause CMOS Resets? Do we still need patching? Link to comment Share on other sites More sharing options...
nyolc8 Posted October 6, 2013 Share Posted October 6, 2013 Yes, use this: sudo perl -pi -e 's|\x75\x30\x89\xd8|\xeb\x30\x89\xd8|' /System/Library/Extensions/AppleRTC.kext/Contents/MacOS/AppleRTC Link to comment Share on other sites More sharing options...
Onixs Posted October 6, 2013 Share Posted October 6, 2013 Anyone has experience with AppleRTC.kext and OS X Mavericks? Does it still cause CMOS Resets? Do we still need patching? Where does it resets, from sleep and restart or restart only? Link to comment Share on other sites More sharing options...
@ROBASEFR Posted October 15, 2013 Share Posted October 15, 2013 Anyone has experience with AppleRTC.kext and OS X Mavericks? Does it still cause CMOS Resets? Do we still need patching? This is the latest AppleRTC.kext (version 2.0) working 100% on my Mavericks GM on Gigabyte mobo EX58-UD5 AppleRTC.kext.zip Good luck 2 Link to comment Share on other sites More sharing options...
Dr. Hurt Posted October 15, 2013 Share Posted October 15, 2013 With the patched AppleRTC in ML, I have to change the RTC length in DSDT to 2. If I leave the default value (4), the system does an instant reboot when waking from sleep (but no CMOS reset). Problem with length set to 2 is that system takes longer to sleep and complains about single ram bank during boot. 1 Link to comment Share on other sites More sharing options...
plprado Posted October 23, 2013 Share Posted October 23, 2013 Hi people. In Mavericks I couldn't patch my AppleRTC manually trough terminal as I did with all the other versions. It simply didn't work. But installing the kext @ROBASEFR attached did the job! Thanks a lot man! Link to comment Share on other sites More sharing options...

holyfield Posted October 27, 2013 Share Posted October 27, 2013 Hi people. In Mavericks I couldn't patch my AppleRTC manually trough terminal as I did with all the other versions. It simply didn't work. But installing the kext @ROBASEFR attached did the job! Thanks a lot man! Actually kext provided by @ROBASEFR is the same, which I got by using this patch on Maverick AppleRTC.kext: sudo perl -pi -e 's|\x75\x2e\x0f\xb6|\xeb\x2e\x0f\xb6|' /System/Library/Extensions/AppleRTC.kext/Contents/MacOS/AppleRTC sudo touch /System/Library/Extensions Its the same patch referred by nozyczek But this patch didn't work for me. With the patched AppleRTC in ML, I have to change the RTC length in DSDT to 2. If I leave the default value (4), the system does an instant reboot when waking from sleep (but no CMOS reset). Problem with length set to 2 is that system takes longer to sleep and complains about single ram bank during boot. I guess it's still some sort of reset. I have similar issue. After wake comp switches off and reboots, but boots Maverick to the after deep sleep/hibernate screen with psw prompt dialog. When I log in, all apps left opened before sleep are opened at state they had before sleep. I got also kernel panic, but after enabling USB fix on boot.plist panic didn't happen anymore.

rgviva Posted November 10, 2013 Share Posted November 10, 2013 This works for me on 10.9 Mavericks: perl -pi -e 's|\x41\x89\xd7\x41\x89\xf4|\xe9\xb8\x00\x00\x00\x90|;' /System/Library/Extensions/AppleRTC.kext/Contents/MacOS/AppleRTC Verify your source file before patching: md5 AppleRTC MD5 (AppleRTC) = 4b1d28ac48a2a7b35ed6b2034e0fd912 This patch completely disables all CMOS writes from AppleRTC kext Cheers!
