* * * * * 1 Votes

Hi guys !

I just tried to install Mac OS X Lion 10.7.3 on Dell OptiPlex 755 with a 7200gs/7300se that I found ! :D

Everything works fine, so I just wanted to share it with you ! ;)


EDIT : sorry guys, I forgot to put sleepenabler for 10.7.3 ! I have just attach it ! ;)

do you have any guide step by step, ive found some on google but in each of them i found a problem, either missing mach kernel, wont boot, will not install on the system, etc
Would you give us some guide. If could thanks very much.
sleepenabler can't work on my Dell Optiplex 755 ,When PC sleep,KB and mouse lose won't work ,so pc can't wake up...Help me !
geez, just reboot.
Could someone PLEASE provide a guide to install this on an Optiplex 755? I have tried with a Gigabyte motherboard, GTX285, etc. just to have a freezing problem and now just want to try and install Lion on my Dell Optiplex 755. I have used U{censored} before, but not sure how or where to start with my Dell. PLEASE if you can help me out, I really want to get going on this again, just don't know where to start.
I can get the U{censored} bootloader to load, but when I select USB (the apple symbol) the screen flashes and then the machine reboots. Any ideas? I tried entering "-v" before pressing "enter" on the usb, but that just sent the boot to 7-8 screens of running terminal text. ANY ideas what else I can enter as text here? or other work arounds???
