A15, but mine's an M1330 and the two machines do have significant differences. Does anyone else with an M1530 use Clover? I don't recall anyone commenting that they use it.

Possibly of interest, I first installed Clover V2 R1000 (possibly older), and now use R1151 and have used a couple versions in between. It updates quite frequently.

Couple things to check:
1. Is your bios configured for hard drives in SATA AHCI mode or ATA mode? Mine is in AHCI.
2. In the Clover installer, under customize, make sure you have an appropriate "Clover EFI" option chosen under "Customize". For my machine it's
"BIOS MBR boot0hfs". The "UEFI boot" option will not work on M1330/M1530 because these machines are too old. Even so, I found it selected in the installer once by default when I was installing on top of Chameleon.

Some of you may have noticed if you used a generated serial to get iCloud, iMessages, etc. to work that iMessages stopped working in 10.8.2.  I researched into the issue, and long story short, you can use Clover EFI boot loader in place of Chameleon to fix the issue.

Install using the installer found here:
http://cloverefiboot.sourceforge.net/

I installed it to my hard drive (of which I have a bootable backup) but a safer less obtrusive way is to install it to a USB drive.

Copy your DSDT.aml into /EFI/ACPI/patched/

Edit \EFI\config.plist.
Below is the config.plist I used:

Replace the two places that have XXXXXXXXXXX with your Champlist generated serial number.

So far everything seems to work the same as before except my memory speed gets reported as 800MHz (I have 800Mhz ram in there but the motherboard runs it at 667 MHz), and restart seems more reliable now.  However I did find it crashed after letting it sit on for a long time.  I don't know if it's a fluke or if this will continue.

EDIT
Once when I woke my computer up from sleep (I sleep it frequently), USB stopped working until I shutdown and restarted the computer.  It only happened once so far, but it's never happened with Chameleon and Mountain Lion.  I remember that being an issue ages ago (Snow Leopard?)

EDIT 2
Had another crash.  Rolled back to Chameleon and had another crash!  I wonder if the crashes are caused by the new AppleHDA or AppleSmartBatteryManager as opposed to Clover...

EDIT 3
Since re-installing Clover and rolling VoodooHDA back to 2.61, I haven't seen a crash.
