Hi, SnickZ.
Thank you for the reply.
I have followed all the instructions in that link to reinstall macOS.
Unfortunately, I was introduced with a whole bunch of problems along the way.
Firstly, Big Sur is currently restricted from from being installed on my MacBook Model because the initial release 11.0.1 has a bug that corrupts the I/O board's firmware in some 2013/2014 MacBook Pro's. So now when trying to install Big Sur i am presented with the following error message "Installation of macOS could not continue. Installation requires downloading important content. That content can't be downloaded at this time. Try again later."
I have formatted my SSD before attempting to reinstall macOS and being greeted with that error message meant i can not reinstall. Anything.
After following the instructions here https://support.apple.com/en-gb/HT204323 i was at least able to install OS X Maverics 10.9.5 which i then Updated to Catalina 10.15.7
I am currently using Catalina 10.15.7 but am unable to update to 11.0.1
I have since been introduced a bunch of iCloud bugs when attempting to sync my data.
Keychain not syncing, iMessages not Syncing, iCloud drive being stuck downloading 2 items, Photos stuck Curating Photos and Layouts.
Anyway, I will simply have to wait for Big Sur 11.1 which thankfully will not be restricted on 2013/2014 MacBook Pro's
Then i will attempt to clean install macOS.
At least Location Services works properly again.
