"Copying Install to this Disk" took 45min (USB 2.0 drive), no visible signs of activity entire time (my USB thumb drive does not have an LED on it) Did not need to do internal date change trick or find any old install packages outside of official Apple download link for El Capitan found 3 days ago.
Terminal "sudo." command: I left Install USB drive named as default "Untitled" after Disk Utility "Erase": that is what worked after other names failed when substituting USB drive name for "MyVolumes.". Initially could not "Mount", i think i had not erased and re-formatted USB thumb drive from FAT to Mac OS Ext (Journaled).
Thanks.Ĭlick to expand.I'm a MacOS neophyte, but i did get it done: i have no idea what i was doing with Terminal command - i just copied / pasted from string i found on a tutorial, only changing "MyVolumes."įor anyone wondering about installation: MacMini 3,1 early 2009, 2.0Core2Duo, 8GB RAM, 5,400 HDD I have never had any trouble with this machine and I am not familiar with diagnosing. I guess my question is can I reinstall the original OS from the disk or the Time Machine and eventually upgrade back to El Capitan? Do I need to reformat the HD to do so? I am at a loss as to how to proceed. I don't care about the data since the last backup. I do have a backup Time Machine of about a year ago. My hard drive had been renamed to diskOs2 and greyed out. I used the original disks to access disk utility. I get the attached screenshot flashed up briefly. If I try CMD R the logo appears and the progress bar does not progress beyond about 10%. Upon restarting I was unable to boot up normally. I believe the error message said no packages were eligible for install. After a few hours of download I tried installing. I was able to use CMD R to reinstall OSX. Just ran across this thread after I tried reinstall of El Capitan on my mid 2007 iMac. I have been fighting with this on/off for a couple of months now and I am completely baffled with why this will not work. I have provided a screen shot of the message that comes up everytime I try and fail. I tried all of these attempts more than once with the same result. I even tried to install 10.11 using my 2009 MacPro Tower on an extra drive I have here.I WAS able to clone my own 10.11 volume from my MacPro to this MBP but of course that was not the final result I was intending because I need a clean/new system not a copy of my own.It looked this was working because it took a while for it to download and install. Tried form the recovery partition, re-downloading the OS directly.
tried from an external drive that had the 10.11 installer.Installed starting from 10.6 and kept installing each subsequent system until I reached 10.10 but when I tried 10.11 no luck.I have tried a few different ways as listed below: I need to repurpose this older MBP for someone else here. I cannot clean install MAC OSX 10.11 on my 2009 Mac Book Pro.
