slow boot ml 10.8.2

7 posts in this topic

Recommended Posts

Good afternoon,


The 17 seconds from video:


On my pc this gray screen with cursor is about 13 seconds. I thought it was the parallels and have so many programs.


I installed the new mount lion 10.8, after the kexts + chamaleon and extra folder.



Without installing anything, did the 10.8.2 combo updates.


But the problem turned gray screen appears.


I took a google search but I can not figure out how to resolve or what the cause is.


Anyone have any idea what it is.


thank you

Can you provide us some information about your system?

Also, did you only install the 10.8.2 update, or also the updates after that? I noticed on my own system, the update 2.0 for Macbook Pro models 2012 reduces performance by 75%, could be system specific.


Boot with -v, and note any error that appears, or take a photo of it and attach it to the post.

What does a video of MacBook Air booting have to do with anything? Sorry for not understanding this, but the MacBook Air sure is pretty! :P

Motherboad: ASUS P5P43TD PRO C2Q Q9400 Memory:2x gskill DDR3 2GB 1666Mhz 7-8-7-24

HD: SATA II SAMSUNG f3 500GB / Realtek Audio: ACL887

Graphics: Saphire ATI 5770 1Gb DDR5 / Keyboard e Mouse: Generic USB

DUALBOOT = mount lion 10.8.1 with windows 8


my pc is detected as a Mac Pro 3.1

Already when I installed 10.8.1 boot slowed and then with 10.8.2 was even slower.


Errors during boot and not have to do with-v I see nothing relevant.

it is possible to see what appears on-v without having to take pictures.

put this flag in your boot.plist: UseKernelCache=Yes , repairPermissions and rebuildcaches with KextWizard/reboot


and change your smbios for Mac Pro5,1

I enabled UseKernelCaches = Yes and then repairPermissions rebuildcaches with KextWizard

Improved 2 or 3 seconds, at this time it takes 32 seconds.


changed the SMBIOS for mac pro 5.1 but gave error "AGPM Contoller unknownPlatForm"

This is normal, AGPM not available on MacPro 3,1, and on MacPro 5,1 it only applies for a couple Nvidia cards. Not an "error". You can look in console.app for any more info, but "looking" for problems can be dangerous and only lead to real problems. Many things that will seem like errors are perfectly normal, but trying to "fix" them may end badly. But really, 32sec? Where is the problem? This is not slow and you can't compare your hackintosh to MacBook Air down to a few seconds of boot time. Remember it doesn't need another bootloader to be in the middle and is a "real mac" for a reason. If using Chameleon, disabling it's GUI and using basic text one instead will shave a few seconds off boot time in most cases.


If this "HD: SATA II SAMSUNG f3 500GB" is hard drive installed on, you should be very happy with those boot times! Your comparing to SSD....on real mac.

    • Hello MaLd0n,   Could you please make DSDT edits for my new Skylake desktop Lenovo M910t    RunMe files: https://www96.zippyshare.com/v/5bgqAiga/file.html
        Thank you very much in advance!
    • Have you tried adjusting the Khz in midi pref pane or editing the info plist to suit your needs. that sometimes corrects weird noise behavior.
    • Hello Mald0n:

      Nice to meet you, I have created a post about my problem on High Sierra before and I was redirected to this guide by Allan.

      As mentioned in the post, I was not able to get pass the login screen at initial boot and the system could not shutdown occasionally.

      However I solve the high temperature problem when I replace the clover folder you provide on first post, currently the cpu temperature is around 5x-6x'c after 10 mins up time.

      Attached is the clover folder, ioreg as well as the send me app, thanks for your help!

      p.s. I notice that your clover boot efi is a old traditional grey apple boot logo, Is there a version of modern dark and white logo one that I could replace with? Thank you!
