Hi, I found I could do it with the Recovery Disk/Partition.
But it’s complaining that the 4TB drive I’m trying to put it on is not big enough. I suspected it must using the MacBook Air drive to store stuff so I’ve made some room on it and will try again tomorrow. 208.95 GB should do it I guess. At one time it said it had About 1,102,053,030 hrs 22 mins to go. (That’s 125,722 average Gregorian years) But about a minute later it continued on to it’s next activity. > On 29 Jun 2019, at 1:34 pm, Brian W Scott <[email protected]> wrote: > > Hi, > > I have a MacBook Air 13 inch, Mid 2011 with Mac OS 10.7.5 El Capitan 10.11.6 > on it. > > I would like to wipe MacBook Air’s drive and re-establish El Capitan on it. > (Why I need to do this is a longer story) > > I have a 4TB USB powered by the USB port it doesn’t have a power supply. > > I was thinking I could use it as an external boot drive while I deal with the > MacBook Air’s drive. > > If it is possible to do the above could someone please point me to some > instructions for getting this done. > > Thank you, > > Brian Scott > > -- The WA Macintosh User Group Mailing List -- > Archives - <http://www.wamug.org.au/mailinglist/archives.shtml> > Guidelines - <http://www.wamug.org.au/mailinglist/guidelines.shtml> > Settings & Unsubscribe - > <http://lists.wamug.org.au/listinfo/wamug.org.au-wamug> -- The WA Macintosh User Group Mailing List -- Archives - <http://www.wamug.org.au/mailinglist/archives.shtml> Guidelines - <http://www.wamug.org.au/mailinglist/guidelines.shtml> Settings & Unsubscribe - <http://lists.wamug.org.au/listinfo/wamug.org.au-wamug>
