Hi, I'll be happy to help with this issue
can you go to the Apple Menu and choose About this Mac and let me know the system details listed there?
Processor 2.4 GHz Intel Core 2 Duo
Memory 2 GB 1067 MHz DDR3
in terms of memory 2GB should be fine for general usage
is it hard drive space which is becoming more of a problem?
removing items from the dock won't remove them from the machine - it just removes the shortcut from the dock
to remove any unwanted applications
if you open up the Macintosh HD icon on the desktop
and then open the Applications folder
let me know when you are there
I am there.
so to remove any application
you simply drag it from here to the trash
Will deleting them give me more memory?
yes, deleting them from here will free up space
If I delete them, will I be able to get them back in the future, should I feel the need?
yes, apps like Facetime etc would be available from the App Store if required
Thanks. I'll delete those and see what happens.
