NapalmCandy Posted December 13, 2014 Share Posted December 13, 2014 Hi, I recently update to Yosemite, I feel that boot up slower than Mountain Lion, I recorded the boot in verbose mode. Please, anyone can help me? I see too many error messages, and load too many kext. Thanks!

NetBladeZ Posted December 15, 2014 Share Posted December 15, 2014 1. What was your install method? 2. Have you done your DSDT and SSDT yet? I stopped using Chameleon because it took a long time to boot. I am on Clover UEFI now. Having said that, I'd suggest you don't do a -f in your boot sequence. One thing I always do is to remove all the kexts that I won't use. Especially the ATi ones if I am using a Nvidia card. Here's my boot up video, not the fastest but it's good enough. Therefore remove the -v from the boot up. It slows it down albeit a little, still makes a difference.

Pike R. Alpha Posted December 15, 2014 Share Posted December 15, 2014 Removing kexts is pointless, and so is the hideous on-screen output I see there. Lines flashing by. Stuff that no one should ever have to see. Ridiculous. In the end you may want a new motherboard with ultra-fast boot support in the BIOS, and a fast SSD, so that even legacy boot loaders like Chameleon/Chimera and RevoBoot are quick enough. The latter boots up Yosemite in about 10 seconds so who needs UEFI... 1 Link to comment https://www.insanelymac.com/forum/topic/303316-how-to-improve-boot-time-video-inside/#findComment-2095174 Share on other sites More sharing options...

My biggest improvement in boot time was changing from Chameleon to Clover. You should also not boot using -v as that slows it down.

NapalmCandy Posted December 17, 2014 Author Share Posted December 17, 2014 I am using chameleon. I tried clover on another hard disk, a clone, times for boot are same. Also I have problems only sometimes that don't want to boot and report errors, with chameleon have same problems. But in chameleon I can boot with flag -v to see that errors. In clover I don't know how to boot with flags. My motherboard has UEFI feature, but I don't know how to use or if I can see diferences om booting Link to comment https://www.insanelymac.com/forum/topic/303316-how-to-improve-boot-time-video-inside/#findComment-2095698 Share on other sites More sharing options...

ballistic Posted December 17, 2014 Share Posted December 17, 2014 What boot options are you using? It looks like you are booting without Kext cache.

NapalmCandy Posted December 19, 2014 Author Share Posted December 19, 2014 What boot options are you using? It looks like you are booting without Kext cache. Yes I am booting without kernel cache, because I read somewhere Yosemite don't use mach_kernel anymore. If I boot with kernel cache then it don't boot, it say "can't find mach_kernel" That is my org.chameleon.boot.plist <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>EthernetBuiltIn</key> <string>Yes</string> <key>GraphicsEnabler</key> <string>Yes</string> <key>Kernel Flags</key> <string>himemory_mode=2 npci=0x2000</string> <key>PciRoot</key> <string>0</string> <key>Timeout</key> <string>5</string> <key>UseKernelCache</key> <string>No</string> </dict> </plist> Link to comment https://www.insanelymac.com/forum/topic/303316-how-to-improve-boot-time-video-inside/#findComment-2096177 Share on other sites More sharing options...

Add <key>Kernel</key> <string>/System/Library/Kernels/kernel</string> 2. Add "kext-dev-mode=1" to Kernel Flags (like so) <key>Kernel Flags</key> <string>himemory_mode=2 npci=0x2000 kext-dev-mode=1</string> 3. Change "UseKernelCache" to Yes (like so) <key>UseKernelCache</key> <string>Yes</string> 4. make sure FakeSMC.Kext is intalled 5. reboot into single user mode using the -s boot flag 6. once at the prompt enter these lines a. /sbin/fsck -fy b. /sbin/mount -uw / c. nvram boot-args="kext-dev-mode=1" d. kextcache -m /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext /System/Library/Extensions e. exit 7. Your system may boot into login screen or restart. Let it do it's thing. Report back If this makes your system unbootable use boot this flag: config=/Extra/boot2.plist And see my post below Link to comment https://www.insanelymac.com/forum/topic/303316-how-to-improve-boot-time-video-inside/#findComment-2096194 Share on other sites More sharing options...
luki1979 Posted December 19, 2014 Share Posted December 19, 2014 ^^^ extactly. This will stop all the kext verification at boot. Link to comment https://www.insanelymac.com/forum/topic/303316-how-to-improve-boot-time-video-inside/#findComment-2096278 Share on other sites More sharing options...
BNZfive Posted December 20, 2014 Share Posted December 20, 2014 If that doesn't work try installing the latest Chameleon @ http://www.insanelymac.com/forum/files/file/59-chameleon-23-svn/ and then use the org.chameleon.Boot.plist I have attached. also make sure you have FakeSMC.kext installed - found @ http://www.insanelymac.com/forum/files/file/266-fakesmckext-yosemite-1010/ Install with - http://www.hackintoshosx.com/files/file/4279-kext-utility-yosemite-258/ -Do steps 5 & 6 above -Once system is up and running do a restart and see how long it takes to boot. report back org.chameleon.Boot.plist.zip Link to comment https://www.insanelymac.com/forum/topic/303316-how-to-improve-boot-time-video-inside/#findComment-2096337 Share on other sites More sharing options...
aphioner Posted December 27, 2014 Share Posted December 27, 2014 Enabling verbose mode can make your bootloader to ignore the kernel cache. So try to boot without -v flag. I mean, just saying...

Allan Posted December 28, 2014 Share Posted December 28, 2014 @NapalmCandy. For this hardware that you using, Clover will be a best choice. 1 Link to comment https://www.insanelymac.com/forum/topic/303316-how-to-improve-boot-time-video-inside/#findComment-2098454 Share on other sites More sharing options...

Allan Posted January 2, 2015 Share Posted January 2, 2015 Ok. Do you try enable TRIM for your SSD? Link to comment https://www.insanelymac.com/forum/topic/303316-how-to-improve-boot-time-video-inside/#findComment-2099773 Share on other sites More sharing options...
NapalmCandy Posted January 2, 2015 Author Share Posted January 2, 2015 @Allan I tried chameleon SSD and Trim enabler, no one works. It say need to reboot before enable TRIM, when I try to enable TRIM it say same again. I think it is because I am using no kernel cache @BNZfive I tried what you sugests, but now I can't boot. It stuck (I add photo). How I said on other post if I use kernel cache then will not boot I tried on a cloned HD so it is not a problem, i can clone again to try other options Link to comment https://www.insanelymac.com/forum/topic/303316-how-to-improve-boot-time-video-inside/#findComment-2099777 Share on other sites More sharing options...
