install lion on mac mini 1.1 with C2D

[ilandmac]

From 10.7.2 to 10.7.3 ?

.1 updated fine for me but .2 put back in the approved devices file so i had to boot to my back up and remove it again. so long as you can keep a clone handy you should be able to boot into an earlier version and remove the file again.

I followed the advice from 4JNA. Great!

I have a question. Is it safe to install the combined 10.7.3 update?

I think that adds back in the supporteddevices.plist so it's a good idea to have a bootable backup handy to allow you to delete the offending plist file.

Hello,

I have followed the steps mentioned above. I have an external usb drive with lion installed, the platformsupport file removed and superduper installed. My mac mini is running 10.6.8 and will not allow me to boot from the external drive. I try holding the option key and nothing happens. I try to select the external drive as the start up drive and I get a flashing circle with a line across it. Am I missing something?

PS my mini is running a t7600 cpu and 2 gb ram...

Thanks!

First make sure that your external hard drive is formatted as HFS+ and has a GUID partition table (under the partition tab in disk utility) use superduper or carbon copy cloner to bake a bootable copy of your mac mini hard drive. Check that you can boot the mini from it before you go further. When you're sure it works take the external hd to a supported mac, and boot the supported mac from the external. Then install lion. Reboot to confirm install was successfull, restart into another startup disk remove the plits file restart the mini from the lion install from the external then clone back to the internal

I have super duper opened, do I choose backup - all files as the option?
