July 2011 I installed Lion over Snow Leopard and got roundly chastised for not first creating a bootable backup. Now having nothing but trouble first with carbon copy cloner then my external Lacie hard drive died.

I know the answer but I'll ask anyway; Lion was a drastic change from Snow Leopard, no more Rosetta, 64 bit from 32 bit etc. Mt Lion doesn't seem to be that drastically different than Lion. So, better chance to just download over Lion and forget about backup???

 

thanks in advance

    Depends on how much you value your data. If it is not important to you, then install away. If you've been operating without a backup all this time, then I don't imagine your data is very important at all. Hard drives die, whether you upgrade or not.

    I guess I now understand what you are getting at.

    If you have a backup, which you do, then you already have your data covered. Now, about your time.

    If you want to keep working like you were if anything goes wrong, then a bootable Clone is the way to go as you can switch right back to that.

     

    Personnally, I have never had a problem with any upgrade, but then I don't use a lot of software that I am invested in that costs too much to upgrade.

    I've got an 8GB core 2 duo (2.66 GHz), NVidia GeForce 256MB that seems to run Mountain Lion just fine.

     

    The newer Macs have four-core chips, so GHz and RAM isn't the only factor.

     

    I'm not certain about the graphics, but I'm pretty sure Mountain Lion will use the graphics card for CPU tasks when it can, which may be what he means by the graphics being an issue.

     

    But, if you clone to the external, then install Mountain Lion on that, you can always go back when you decide it's not zippy enough or any other incompatibility.

    If you want to clone then use SuperDuper - easy and painles but not free - about $20 - http://www.shirt-pocket.com

    You use what ever you want - just my opinion.

    You can use whatever you want for a backup. But, if you want a bootable clone, you must use some form of cloning software.

    Carbon Copy Cloner wasn't painless????

    Pick the Source, Pick the Destination, click Clone. That's pretty non-painless. What did you do to make it painful?

    I wasn't clear. Time Machine does not make a bootable clone. That's what I meant when I stated,

    But, if you want a bootable clone, you must use some form of cloning software.

    Did you format your external drive?

     

    If you plugged it in and used it for Time Machine, then TM takes over the entire drive. If you want to use it for something else as well, then you would need to partition the drive first and that will result in having the drive erased. You do not need any software that might be included with the drive. Open Disk utility and choose the external drive. Choose Mac OS Extended (Journaled) as the Format and, under the Partition tab, click on Options and make sure it is GUID. You can then choose to keep it as one Partition or add one or two. Click Apply. Your hard drive will now be erased and then ready for a clone.

     

    Before upgrading, make a bootable clone. Then buy/download ML - you can install it on the internal or the external clone - when the download is finished, either find the Installer in the Applications folder and make a copy of it to park it in another folder/drive for safekeeping in case you need to reinstall - or simply install it.
