I am considering to upgrade to Mountain Lion from Lion on my iMac (21.5-inch, Late 2009).

I was slightly worried about upgrading to Lion when I was using Snow Leopard, so I installed Lion on a new partition - This has worked perfectly as Lion removed support for a lot of my applications I used. I doubt I will do the same thing this time round as I am running out of room! (And I don't think multiple partitions on the Mac would be healthy... It stands at: 100gb Windows XP, 100gb Snow Leopard, 300GB- Lion being my 'base') I think yet another partition would mess up my mac.


Another concern of mine is speed. As my model is getting to be slightly old, I'm not sure if it will be able to run Mountain Lion smoothly.

Would Mountain Lion run smoothly with these specs (nothing out of the ordinary)


Processor  3.06 GHz Intel Core 2 Duo

Memory  4 GB 1067 MHz DDR3

Graphics  NVIDIA GeForce 9400 256 MB


I am also concerned about the use of my applications. My music mentor let me borrow their copy Logic Pro to install as I cannot affort to download it for my university studies. I am worried that, if I upgrade, I would loose Logic Pro completely. Whether it being erased, being incompatibile, or even having to reinsert the serial number. I have lost contact with my mentor so I would have no way to get it back.

    If it runs Lion it will run Mountain Lion. If you are using another persons copy of Logic Pro then that is illegal. We cannot advise you regarding that except to recommend you purchase your own copy or see if there is academic pricing available through your university.


    Additional partitions will not "mess up your Mac." It will simply reduce the amount of space in the partition from which it is derived.

    I didn't realise it was illegal, my mentor used to use my iMac for Logic all the time as his computer failed, I suggested that he could use my iMac until he raised enough money to buy a new computer. I would use it for my studies, and he would use it for recording his own music.


    I only ask about the speed difference as the reviews on the Appstore keep claiming that there is an significant drop in performance from Lion.

    Couldn't say about speed of Logic. I don't use it. Given that Mountain Lion is as fast or faster than Lion I can not comment of the so-called reviews.


    Surely, you know that if do not pay for commercial software and use someone else's copy, that constitutes piracy. Much the same as my putting my name on a piece of your music.
