how to do a disk defragment on a mac book

Not exactly easy. I used to do that back in the ancient days of OS 1 - 9.

So Charles Babbage's difference engine runs Windows?

I'm confused...😕

All drives in a mac, solid state or hard, are digital.

I meant to say SSD's don't fragment as they use flash cells, so don't have to be read sequentially as apposed to a disk?

I mis-used the word "digital", i meant "flash technology"

You should telepathic by now with all those points, jeeze ! 😉

Joking aside, I will read what I'm meant to say before I write what I'm not meant to say in future ha

Ok, cheers for that buddy. I got his humour 😁 lol

I beg to differ with you I think the general consensus is that a Mac is a computer.

It's 15 percent until you reach 10G, then it's enough.

This means you don't now the answer i assume...

I hope somebody has the anwer.

thx for making this clear!

may i conclude 'for normal usage' includes OS X's auto-disk defragment?

I gave you a useable answer but all you have is attitude I'm out.

sorry Csound1, but i could'n do anything with your answer. Can you translate it please.

Sounds to me like: it's 15 euro's until you reach 10 dollars, then it's enough.

double post deleted. Don't know how to delete post totaly.

If you wish to defragment then do so, your choices are just that.

I meant to say at the beginning, "I like the way you broken down into an A and B choice." Siri dictation doesn't always work.
