@dosdude1 When I run the post install patcher, only the usb installer shows up in the drop down list, not the disk I installed Sierra to. Do you have any tips as to what I can do?

Looks like it won't be needed. I recreated the usb installer with another usb stick and voila - it works on my late 08 (5,1) again. Maybe it'll depend on the stick...?

Command + R not work with MB Aluminum Late 2008 and macOS Sierra PB1.

That won't work at this point, as the recovery partition can't be modified. I'm working on that, though.

Ok, well I've updated the tool... Just recompiled and uploaded pretty much. Couldn't really find anything wrong. One thing to make sure of is that the language on the system you're using to create the USB drive is set to English. Also, if it's not working on one particular USB drive, try it on another.
 
@dosdude1...the language on my system is English and I tried it with my both external drives WD passport 320GB... it's not working and same thing, Prohibited sign on booting after patching macOS Sierra

Ok, one more possibility on what the issue could be. Go to your Finder menu, select "Go" then "Go to folder". Type "/Volumes", and make sure there's nothing there named "OS X Base System". If there is, unmount or delete it, then try running the tool again.
 
@dosdude1 Im reading the thread and I did that as well before booting a couple of times....Im downloading again the macOS sierra from the link you gave me, and Im going to try again with the patcher that you just updated.... what I dont understand is:

1. in your video you say the patching is complete in 15 to 20m depending of the drive, each time I patch it completes it in 3 minutes tops... is it normal?

2. I placed the install macOS sierra public beta in the applications folder, shall I patch it directly from the dmg?

3. why is the patching completing correctly and then I cant boot from the OSX base system?

Something is wrong if it's only taking like 3 minutes to patch. It should take much longer. Is it prompting you to enter your password? If it is, it should restore the Base System image and create a volume named OS X Base System. If that volume doesn't mount, the patching will fail.
 
I've tried reinstalling using the same usb, a different usb and they have the same result - the installer gets to about 11 mins remaining then reboots instantly to a black screen which loads the forbidden screen.

Time to restore from a back up....

Ok, can you run the patch again, and when it completes, open Terminal and type "diskutil list". Send me a screenshot of the output.

I've a question. When a new update of Sierra comes out from the store we need to re download the full iso and re patching it or we can do the update from the store without any problem ? thanks in advance and thank you so much for your hard work ;) I've got an iMac early 2008 24"

Good question... I would like to know the answer too

Huh, the drive is there... That's really weird. Can you try doing it one more time, but this time send me the output of "ls -al /Volumes"?

You should be able to just update, and re-run the post-install patch.

same thing, patches in less than 3m
