Use Apple Time Machine to make a backup of your Apple Mac computer.

For the very best speed and performance when backing up your Apple Mac computer to Apple Time Machine, use a external USB USB-C storage volume.

Even if you have a Apple Mac computer that has USB A ports, buy a external SSD USB and USB C storage volume.

so if you decide to replace your Apple Mac computer you can use the USB C external storage volume to transfer the data from your existing computer to your brand new Apple Mac computer, new Apple Mac computers have USB C ports.

How to use Apple Time Machine backup on your Apple Mac computer.

You can back up an Apple Mac computer using the built in Apple Time machine software to:

Either an external storage volume • to as NAS (network attached storage volume).

The external storage volume can be a USB-C drive with a USB adaptor cable for older Apple Macs.

Thunderbolt external drive for the ultimate backup speed, however USB C today is cost effective!

The storage drive technology can be either SSD (solid state drive) or a conventional mechanical drive.

  • Choose an SSD external backup storage volume if you travel with a MacBook Air or MacBook Pro laptop computer!
  • If you are good at dropping things, we all drop something at times, then if you are travelling with a Apple MacBook Air
  • It makes sense to use a SSD solid state drive vs a mechanical storage drive for your Apple Time Machine backup!
  • IF you have 1Tb of internal storage on your Apple Mac computer, we recommend a 2Tb storage volume.

Make sure that the non-Apple Mac software will run with a new macOS operating system software upgrade.

Starting with macOS Catalina, macOS Catalina only runs and supports 64-Bit technology.

Older macOS operating system software versions were 32-bit.

So one example is Microsoft Office 2011 for Mac, Microsoft Office 2011 for Mac will not run on macOS Catalina. Microsoft Office for Mac 2016 or Microsoft Office for Mac 2019 is required.

If you are using a Apple Mac computer, and you are using only the pre-installed macOS software, then upgrading to macOS 64-bit is rather straightforward.

The exception is if you have an old printer, some old printers will not work with macOS Catalina or newer without a firmware upgrade, or a printer software driver upgrade.

Most if not all consumer retail printers will not have a problem, professional printers and rips will often have a problem with a macOS upgrade.

Once you have done a 32-bit to 64-bit Apple Mac computer software audit on the non Apple Mac computer software, you can then perform a macOS operating system software upgrade.

How to obtain an older version of macOS?

Apple has written technical documents on how to obtain older versions of macOS.

macOS how to get old versions of macOS

The Apple technical document starts with advising on compatibility, for example a Apple Mac mini 2011 computer comes with macOS Lion 10.7.5 and can support macOS High Sierra.

Apple has listed all of the Apple Mac computers in the compatibility guide.

If you have a Apple Mac computer that is 2009, 2010 or even 2011, maybe now is the time to consider a new Apple Mac computer?

The Apple macOS 10.7.5 and macOS El Capitan can still be used, however, for internet use, trying to use macOS 10.7.5 Lion today is not going to work well on the internet.

Even macOS El Capitan is not going to fully support the internet, and even your Apple ID or Apple iCloud account.

We consider macOS High Sierra and macOS Catalina the best macOS for older Apple Mac computers that are compatible with these Apple Mac operating systems.

For 2014 and newer Apple Mac computers macOS Big Sur or newer is recommended, at the time of writing this article.
