#INSTALL OS X EL CAPITAN ON NEW SSD WITHOUT DISK MAC#

Turn your Mac on, while holding the CMD + R keys down.

Also, it is advised to make a time machine back up of your computer if possible before following the procedure. To reinstall your Mac's OS without an installation disc you need to firstly make sure that you keep your Mac turned on during the whole procedure, and that your Mac is connected to the internet.

#INSTALL OS X EL CAPITAN ON NEW SSD WITHOUT DISK HOW TO#

In this article we will show you how to reinstall Mac OS without disc. It must have been there in the clone too, I think that used to be a problem in previous versions of SuperDuper.MacOS includes a recovery partition that allows you to easily erase all data on your Mac and reinstall your OS without an installation disc. High Sierra reinstalled, recovery partition is there. Then maybe I’ll trade in one (possibly two) of the remaining machines. No experiments on the 13', which is itself a clone, so it may not have it, since that’s my main machine for the moment, until I’m fully satisfied that the “new” 2015 11' is working without fault. I’ll run the command in Terminal again when it’s done. I hadn’t checked if there was a recovery volume in disk utility, but it didn’t go into internet recovery so I suppose there was). It actually says it has four volumes:Ĭurrently reinstalling High Sierra on the 2015 11' (I hope you can still follow which is which, this is the latest one, the “successor”! ) after entering recovery mode with cmd-R.

#INSTALL OS X EL CAPITAN ON NEW SSD WITHOUT DISK INSTALL#

Ran it on the 2012 11', which had a clean install of High Sierra after the SSD change and it has it. I hope my message was clear enough and apologies for perhaps asking very basic questions. I’m also wondering if I could just dump the whole clone onto the SSD (by using the clone as a startup disk and cloning onto the SSD with Superduper) or without a proper installation (the SSD is empty now) it will act up eventually? I know there’s the option of creating a bootable High Sierra installer (that is as far as I want to go), but it didn’t work (I will try again though).

Should I have stuck to Mac extended, installed El Capitan and then reformatted to APFS for High Sierra at some point? I’m a bit confused. Was that a mistake? Internet recovery gives me the same results as before the reformatting. If I start it from a clone (from the 13') I can see the SSD and I have reformatted it in APFS.

However, internet recovery won’t find me anything more recent that El Capitan. I know these SSDs work from 10.12 onwards, provided the computer had at least High Sierra installed before (it did), so that it could get its firmware update. Command-Option-R gives me a 5101 F error and Shift-Command-Option-R gets me to disk utility with the option to install El Capitan (10.11), but the SSD is not seen. I have now replaced the SSD with a 1TB from OWC and I can’t get it recognised in recovery mode.

I’ve tried it, it worked (it had Catalina on) and it seemed quieter. I have now decided to buy a second-hand 2015 11', which came with a 256GB SSD and 8GB RAM. The 13' was actually meant as a temporary replacement for my 11', which I still find very handy to carry around (I have a 27' Thunderbolt display at home), while I upgraded it from 500GB to 1TB and ran a few tests (loud fan). Those who have read my messages before will know that I currently own: Here’s another episode of my Macbook Air love saga.
