New SSD – Mac OS High Sierra Installer

LAST UPDATED: Wednesday 30 MAY 2018

For most Mac users, mechanical hard disks are going the way of CDs, DVDs and floppy disks. Even USB Flash drives seem redundant for all but temporary transfer storage when compared to SSD, and small files are just as easily transferred via email, with larger file transfer possible using Google Drive or DropBox.

Just as soon as you purchase a new SSD drive, do the following:

  1. Before you do anything with the new SSD drive, use Apple’s Disk Utility to create an extra partition on the SSD to make it trivial to boot if the main partition has a boot issue. 6Gb should be sufficient, so will not take too much space away from the SSD – the benefit will far outweigh the cost and will be a life-saver in the event of a drive problem. Here is a detailed article detailing how to do this if you need help:                    How to create a bootable macOS High Sierra installer drive
  2. If you just need help locating High Sierra, see How to download macOS High Sierra
  3. Install the free application Install Disk Creator, to reformat the partition on the SSD created in the previous step (details are also shown in the link in Step 1. above)

Please do not hesitate to contact me via the contact form on this site if you have any issues with any of the above. There’s always a trade-off in a blog in making a description too verbose versus keeping things concise, so don’t be shy to ask!


P.S. I wrote this blog post after purchasing an external 1Tb Western Digital SSD drive I bought very cheaply from Maplin. To my disbelief, Maplin has no working website! It has a site, but only as a holding page for contacting the administrator. In my humble opinion, Maplin went into administration precisely because many potential customers moved over to purchasing over the internet. I believe the administrators of Maplin are not adequately internet-savvy, in my humble opinion, so, surely, the very last thing Maplin should close down is its website!


Maplin is in administration so everything is going very cheap – they are even selling shop fittings – I managed to pick up five high-quality LED ceiling lights for a bargain price!


I will either install these lights in my garage or else sell them on eBay!
