So, as the title says, i got my dads old iBook g4 mac about half year ago and I have got since that many problems with software. Unlike with windows and ubuntu, I don't know how to use mac so I made my decision to ask some help. Here's some typical problems with my computer. -Safari and other internet browsers have started to crash down in normal use. Other softwares also do this sometimes. -Everything happens very slow. When I type e.x. url, the letters appear 2-3sec after I have pressed them from my keyboard. Downloadtimes are also huges.(downloaded this forum like 3-4min) (my internet connectivity can't be the reason, 'cause my other laptop (ubuntu) downloads sites under 2sec) -Air inside my laptop heat up fast. (I can warm my fingers with it just after couple ten minutes using) -Lately I've noticed that I can't update my programs ex. firefox. Do you ppl have any idea what's wrong in the computer or the user? Thanks for help already.
