themacmeister Posted November 2, 2015 Share Posted November 2, 2015 I just upgraded my 10.9.5 Mavericks install on this laptop to 10.11.1 (posting this from the new install) I used the same technique as my Yosemite upgrade, which can be found here... http://www.insanelymac.com/forum/topic/300289-acer-aspire-4752-1095-guide-with-kextpack/page-2?do=findComment&comment=2170828 The only real difference is in the creation of the USB stick. The usual tool everyone uses creates a GUID EFI USB stick, which is unusable on this laptop... You will need to use Disk Utility to create a Sparse Image of the MAIN PARTITION, and then restore that usb.sparseimage to restore to MAIN PARTITION of OTHER MBR formatted Mac OS Extended (Journaled) USB stick. You can then safely install Enoch's custom Chameleon build onto this USB, and boot with csr_active_config=3 + Kernel_booter I hope to get a more thorough guide together when I find time... I am still using old SSDT/DSDT from Mavericks, and all is good, except: No Audio (obviously) No USB 3.0 (this will be challenging to fix) Computer restarts instead of shutting down (annoying, but hitting the power button quickly shuts it off instantly). More news as it happens... Link to comment Share on other sites More sharing options...
