iMac 7.1 2007 tips & tricks

Install High Sierra

I just followed the instruction from http://www.dosdude1.com/highsierra/ and also http://dosdude1.com/sierrapatch.html.

First, hardware upgrade, choose a good CPU, open the iMac and install it.

sierra patch and usb osx installer

I discovered that if you used your USB for linux shit, and create a NTFS filesystem, and follow the dosdude1 instructions, the process exit with some errors when unmounting and remounting the usb drive, especially creating the patcher! What I had to do is to wipe out the usb drive BEFORE creating the ntfs partition. I used dd if=/dev/urandom of=/dev/sdbX bs=4k and let it go for a while.

preserve your usb drive

it will be useful when you forgot to avoid installing upgrades and your wifi card will be screwed up and you will obtain an ugly "wifi not installed" message!!!!!
