How much is 4gb of ram enough for?

4GB in Mavericks is double worth what 8GB is in earlier OSX.

others have already done so, but you're free to test them yourself and learn objectively.

What about Adobe products and MacBook Air? Are these products useful or even needed in addition, to the contents that comes with a Yosemite 10.10.3?

In more than one conversation Adobe products are remarked to 'take up a lot of space' --

Is Adobe Flash Player already part of the Yosemite when purchased?

What is the Acrobat and Acrobat Reader and should they be downloaded onto a Yosemite, even if they are free?

Thank you for you time and consideration.

With the Yosemite upgrade, are these helpful links you offer still applicable?

If one upgraded from a Maverick does what is written to apply to that machine

hold true now, with the Yosemite upgrade?

Adobe products are required only if you need them for a specific task, you don't need Acrobat, preview will open pdf files. Use the Mac as it comes to begin with, you will discover new software requirements as you need them.

The memory management system in Yosemite is the same as in Mavericks, on the OS level most things apply to both OS's. 10.9 and 10.10

Did Adobe Flash Player come with the Maverick 10.9.4? I downloaded an upgrade on flash player but don't know if the machine had

this app on it to begin with.

My husband has a new MacBookAir Yosemite 10.10.2 and was told by Apple Care that the Adobe Flash

Player was on that machine to begin with.

You say Preview does the job of Adobe's Acrobat, where is Preview (in iCloud with Yosemite?)

what does it do, is it something 'in the background' or that a user makes use of in an interactive way?

I believe that Flash has to be installed on a new Mac, and Preview is an app, it is in the Applications folder. It opens (among other things) pdf files, just as Acrobat does.

Note that fake flash installers are rife, never update flash from anywhere other than Adobe's website

When I read Plotinus comments I find them helpful. In terms of 'enough space' question, I am using a MacBook Air 13" Yosemite 10.10.3 and MacMail version 8.2 (2098). In the mailbox column of Mail under Archives there are two : Archive: "On My Mac" mailboxes, both save the same material - isn't this taken up twice the space it needs to? -or not? Can remember if just noticed this, or it has appeared since Yosemite upgrade. Cannot remove and have only one of these mailboxes remain, any suggestions? The only thing that I can think of, is only to use Achieve: iCloud

to save space on computer. I know I could use Gmail but I really like MacMail program. Thank you for your time and consideration.

good reminder -😀
