On the installing part, it just say 16 minutes remaining and nothing happened for 8 hours. And after that I decided to try the CNet tips. The backup was successfully done by SuperDuper but when I instal the SSD to my MBP and the El Capitan stucked on loading screen forever. Trying to install Mac OS X El Capitan on SSD. I am trying to install El Capitan on an ssd for another mac. I am using my girlfriends current MacBook Air 2017. Since I had so much trouble with a usb boot drive, I decided to install El Capitan directly onto the ssd (by using a usb to SATA adapter) then put it into the iMac.
Install Mac Os X El Capitan On New Hard Drive To Windows 10 Oct 01, 2015 An alternative approach is to create a dedicated installation drive from the El Capitan installer, and use that to install the upgrade. Install El Capitan OK, now you can click that Continue button in the installer window. (If the installer isn’t running, go to your Applications folder and double click the Install OS X El Capitan. Depending on what version of Mac OS X is on the computer right now, you can try to use Recovery Mode (Command + R on boot) to reinstall. A better option may be to use a USB installer drive for El Capitan or whatever version you are hoping to reinstall.
My MacBook Air is running a 120GB SSD drive so I don’t want my hard drive full of excess things I don’t need. I just noticed after El Capitan that I lost a lot of space. I only had 10GB free. To run well a mac hard disk needs at least 20% free. Here’s how I freed up some more space.
I ran Disc Inventory X to see where the excess space was taken.
1. Remove old iPhoto library.
Look at this screenshot from Disk Inventory X: The pink section surrounded by the yellow line is my old ‘iphoto’ library. The large turquoise section to the left is the new ‘Photos’ library. El Capitan came with a new app called ‘Photos.’ The new Photos app imported my old iPhoto library, but it didn’t delete it! They are the same photos, the entire library has been duplicated. Deleting my old iPhoto library released almost 7 G of space!
To find the file just right click on the box and select ‘reveal in finder’:
This took me to the following folder:
Free online convert png to icokeyclever. I just dragged this to the trash and saved 6.6GB.
While I was at it I went to my ‘Applications’ folder and deleted the old ‘iphoto’ app which took up 1.7GB.
I could do this pretty confidently because my macbook air is my second machine, all my photo’s are only home computer if anything goes wrong.
2. Gmail ‘All Mail’
This huge multicoloured box turns out to be the Gmail ‘All Mail’
I discovered 15GB of gmail data in Apple Mail. Yes Apple mail now by default seems to download the gmail ‘All Mail’ folder which included every email you’ve ever deleted on gmail. The ‘All mail’ folder had over 17,000 emails in it. No wonder my internet usage was high last month – my laptop must have downloaded the entire 15GB of emails from gmail.
Install Os X El Capitan On New Hard Drive
Thankfully it was a simple fix.
Here’s how to disable the ‘All mail’ folder from being downloaded to your Macintosh.
Go into Gmail.com, then go to Settings on the top right menu, then under the ‘Labels’ tab I changed ‘All Mail’ to ‘Hide’
Install Mac Os X El Capitan On New Hard Drive
I still needed to delete the files from the hard disk manually.
I am using OSX El Capitan, and Mail version 9.1. I am not sure what other versions of mail have this problem.

Install El Capitan On External Ssd
The were some other files I found with Disk Inventory X, (Old installers, old apps, some movies) and when I deleted them all in total I recovered 30GB!
I am using Macbook Pro Mid 2012 13' with 128GB SSD. The latest installed version of OS X was El Capitan which crashed during a Sierra upgrade.
Internet recovery mode worked somehow to land me to install download and install a new OS but it's Mountain Lion, which came installed when I bought the Macbook few years back However, it's rejecting to install on current SSD drive as shown in pic.
I have another 320GB HDD, so is this the only way to reinstall? First I do a fresh install of Lion on the external HDD? What I should I do?
What is a step by step procedure as all I want to do is run OSX on SSD drive but keeping all my older data. I can not afford to wipe it.
El Capitan Install Dvd
However, I did back up some of its backup onto my PC. If I install Lion the HDD can I then download Sierra and create an install disk to update/fix/install corrupted OS X on SSD?
