mickeyd453 Posted November 30, 2014 Share Posted November 30, 2014 Hi I am running a system that was upgraded from 10.8 > 10.9 and most recently to 10.10 and in fact now 10.10.1 Before moving to 10.10 it was super stable but since moving to Yosemite there are times when the machine hangs on boot and i have to power cycle it at which point it generally boots OK. Once booted it is 100% fine and stable. I would say the boot hangs occur maybe 30% of the time therefore 70% of the time its no problem. There are no differences during these random boot failures and no hardware is added or removed. About the only thing i can see in the logs is the following and during a -v boot i noted this is where the machine seemed to hang, however succesful boots also seem to have this 'error' MAC Framework successfully initialized Nov 30 00:22:35 localhost kernel[0]: using 16384 buffer headers and 10240 cluster IO buffer headers Nov 30 00:22:35 localhost kernel[0]: IOAPIC: Version 0x20 Vectors 64:87 Nov 30 00:22:35 localhost kernel[0]: ACPI: sleep states S3 S4 S5 Nov 30 00:22:35 localhost kernel[0]: pci (build 00:11:20 Sep 19 2014), flags 0xe3000, pfm64 (36 cpu) 0xf80000000, 0x80000000 Nov 30 00:22:35 localhost kernel[0]: waitForSystemMapper Nov 30 00:22:35 localhost kernel[0]: Backtrace 0xffffff80008e5f54 0xffffff80008e6a64 0xffffff80008e72f6 0xffffff80008e9e1d 0xffffff7f82231245 0xffffff80008b57ed 0xffffff80008b530f Nov 30 00:22:35 localhost kernel[0]: Kernel Extensions in backtrace: Nov 30 00:22:35 localhost kernel[0]: com.apple.driver.AppleRTC(2.0)[B89EF128-7207-3CB1-B843-D0BE6499B7A7]@0xffffff7f8222f000->0xffffff7f82239fff Nov 30 00:22:35 localhost kernel[0]: dependency: com.apple.iokit.IOACPIFamily(1.4)[70E2B65E-A91A-3522-A1A0-79FD63EABB4C]@0xffffff7f81909000 Nov 30 00:22:35 localhost kernel[0]: FakeSMC v6.11.1328 Copyright 2014 netkas, slice, usr-sse2, kozlek, navi, THe KiNG, RehabMan.

I tried the 10.9.5 IOACPI rollback but it seems to make no difference. thanks!

aww Posted December 2, 2014 Share Posted December 2, 2014 You need to list, your hardware, cpu ,MB, Graphic list your loader and loader version. Current Clover is very good for older machine in MBR installation, no so go with SOME UEFI machine. Chameleon Current Version Ok for legacy machine. I suggest you use. Clover 2795 for UEFI Chameleon 2510, Clover 3033 for legacy machine.

bigben1 Posted December 3, 2014 Share Posted December 3, 2014 remove applertc kext from /s/l/e and install patched rtc kext, delete fakesmc kext, nullapplecpupower management kext. reinstall again fakesmc kext for yosemite and nullapllecpu power management kexts. Evoreboot kext delete kernel cache, use following command in teriminal sudo rm -r /System/Library/Caches/com.apple.kext.caches use kexthelper to rebuild caches, and reboot.

mickeyd453 Posted December 4, 2014 Author Share Posted December 4, 2014 Hi Thanks for the help - When i removed AppleRTC.kext the machine would not boot at all even if i had ElliottForceLegacyRTC.kext installed. Is this the kext you were referring to when you say patched rtc kext? I restored that kext and i am back at the same error, even though the machine boots. When i remove AppleRTC.kext the boot stops at the following Thanks for any further advice!

aww Posted December 4, 2014 Share Posted December 4, 2014 you do not want to list your HW and loader, Let me guess, installer with UNI-{censored}, I-{censored}, N-{censored}. Since 27xx series, Clover loader is able to boot legacy machine, without EVOreboot, PatchedRTC. Use Generic USB installation Guides. HERE. Use Clover.

mickeyd453 Posted December 5, 2014 Author Share Posted December 5, 2014 Hi - Nope not censoring anything - bootloader is latest chameleon 2400:2404 according to chameleon wizard and it was installed via UNI-xxx as myhack 4 was not available, my usual method. Hardware is 3.32 GHz Intel Core i5, 16 GB 1333 MHz DDR3, NVIDIA GeForce GT 610 1024 MB running on a Dell Optiplex 980 SFF I have never played with clover and as everything runs good, generally, under chameleon then i thought i'd stick with that. thanks!

holyfield Posted December 5, 2014 Share Posted December 5, 2014 Once again, no hassle with Clover. I switched from Chameleon to Clover, less patching/hacking and everything runs even better than before. Clover is really good boot loader and will become even better. Clover provides very solid configuration system too. So, my suggestion, use Clover.

mickeyd453 Posted December 13, 2014 Author Share Posted December 13, 2014 Hi Well i finally got around to trying clover - i installed it to replace Chameleon and now when i select boot OS X then the screen just goes blank. Booting using verbose mode also produces nothing but a blank screen - This is booting from a USB HDD All suggestions i have found so far dont get my far so any ideas? cheers Link to comment https://www.insanelymac.com/forum/topic/303014-10101-hanging-on-boot-30-of-time/#findComment-2094626 Share on other sites More sharing options...
mickeyd453 Posted December 14, 2014 Author Share Posted December 14, 2014 Well i can get it to boot but there is a huge delay from picking the disk to boot from and then actually the machine booting - like 20 minute delay I will start a new thread on that one but interestingly the backtrace issue is still present so it seems clover does not help anyway cheers Link to comment https://www.insanelymac.com/forum/topic/303014-10101-hanging-on-boot-30-of-time/#findComment-2094999 Share on other sites More sharing options...

avin7000 Posted December 18, 2014 Share Posted December 18, 2014 I suggest you use. Clover 2795 for UEFI Chameleon 2510, Clover 3033 for legacy machine. Can you elaborate? You mean do not use clover 2795 on UEFI boards?
