But as a rule of thumb, the effort of performing the installation compare with the marginal cost of bigger RAM modules means that it's worth maxing out your Mac's RAM in one go. That will often mean removing the existing modules and replacing them.
It's a good idea, though not essential, to buy all the RAM you fit at the same time from the same manufacturer. If you decide just to fill empty slots, the same applies. And you should pair RAM modules of the same capacity, if possible. The biggest hurdle will be whether it is possible to upgrade the RAM in your Mac, many modern Macs cannot be user upgraded.

Few aspects of Macs cause more arguments than the one about what to do at the end of the day: shut down or sleep?
The old argument of leaving a computer on as much as possible was based on the wear and tear of restarting the hard drive, but the restart argument rests on more than just this.

If you run maintenance or backup scripts at night, your Mac can always be set to shut down after these.
Restarting your Mac clears the caches and shuts down applications. The result is a Mac that's refreshed and should perform better.

Most of the current crop of Macs come fitted with SSD storage in place of a hard drive.
