Hi there everyone,

Have you ran Disk Utility> First Aid on your mac, if not restart to your Recovery Drive and open

Disk Utility there and run First Aid. If any errors are encountered run First Aid until they clear.

Restart normally and try again.

It may also be worth trying a Safe Mode restart.

https://support.apple.com/en-gb/HT201262

Safe mode takes a long time to start up so be patient, it is carrying out repairs and clearing caches.

You could try installing whilst in Safe Mode or restart normally and try again.


If you are running Mac OS X El Capitan and want to upgrade directly to macOS Big Sur you need at least 45.5GBs of free space.


Personally I would not recommend upgrading directly from El Capitan to Mojave, Catalina or Big Sur,

there have been reports of the installation stalling, probably due to the install trying to convert the

HFS+ file system to the newer APFS file system.

I would recommend upgrading to macOS High Sierra first as this should give you instructions

on how to update the firmware on your mac so it can convert to APFS.

Whenever downloading from Apples Servers make sure mac is connected to your router via cable.


Open your Safari browser and click on the link below,

How to get old versions of macOS – Apple Support

Go to the Download OS section and click on macOS High Sierra.

This will redirect you to the App Store High Sierra page it should say Get or Download.

This will download the Install macOS High Sierra.app to your Applications folder the download

is 5.23GBs in size.


Before upgrading make a full back up of your Mac.


Check that third party apps you use have updates available for the new OS.

https://roaringapps.com

Check that your printers/ scanners etc have updated drivers and software available for the new OS.


Connect your mac to your router via cable rather than rely on WiFi.

Do not use your mac while it is downloading

and do not use any other devices that share the same internet connection.


If the App Store says ‘Open’ then it is detecting a previous download of the install app

go to the Applications folder locate Install macOS High Sierra.app.

Move it to the Trash, empty the Trash.

Restart, click on the link again, the App Store should say ‘Get' or 'Download'.

Once you have upgraded to High Sierra you can then decide if you want to upgrade to

Mojave, Catalina or Big Sur.


If you are considering upgrading to Catalina or Big Sur be warned they do not support 32bit apps.

Your Mac is probably running 32bit apps and these will need to be updated to 64bit apps,

some updates may be free, some may be paid. Use this app to discover which apps you have

are 32bit, https://www.stclairsoft.com/Go64/ then contact the developers of the software to see

if they are offering 64bit updates.
