Sep 29, 2015 8:21 AM in response to pokeymailby The Art Of Sound,Don't upgrade OS X on your System drive.... LP7 will not function correctly with 10.8 or later...
Instead, use an external Hard drive as a boot disk and install the updated OS X version on that and boot to it when you need the latest OS X features like modern iTunes etc...
You may find this support doc of use... but search the web for more detailed information on how to achieve this if needed.
How to install OS X on an external drive connected to your Mac - Apple Support
Then you will get the best of both worlds leaving your original configuration intact.

Sep 29, 2015 8:27 AM in response to pokeymailby Gimmac,I'm afraid it won't. After a long break from Logic I tried to install Logic Studio (an upgrade from L7) on a Mountain Lion Mac Pro, and it wouldn't even start. IIRC, it said something like "can't install PPC code apps". Best you can do is using a second HD for ML and leave your music HD untouched.

Sep 29, 2015 1:45 PM in response to pokeymailby logic79,I have been running Logic 7.2 or actually 7.2.3 (You may need to update), with Lion 10.7 for about three years with no issues at all. About three months ago I upgraded OS to ML 10.8.5 and it has been as stable as it was with SL 10.6.8. I also run Logic Studio V9 with no issues with 10.7 and now 10.8.5.
Before I installed Logic 7 and 9 I installed Rosetta from the extras folder from the SL 10.6 Install disc. I runs a program to see if all is compatible.
It was so I installed it.
I am also able to run Final Cut Pro 6 and other earlier apps, with L 10.7 and ML 10.8.5.
If it works for me it should work for every one else.

or not....
Seriously, a number of people have tried this hack found they had some major issues later on.... and so that's why it's not recommeneded.. It has worked for a few.. but for the majority it ended up causing long term issues that were, for all practical intent and purpose, impossible to resolve.
With the lower cost of external HDs these days its safer in the long term, to use the dual boot system.
Also note: Many users who updated to ML with LP7 or 8 had the "Black Bar in the Arrange window" graphical corruption issue which cannot be resolved it seems... without upgrading to LP9 or LPX.

Sep 29, 2015 3:43 PM in response to The Art Of Soundby logic79,Hi Art of Sound,
I have followed your postings and advice for some time with the utmost respect and have gained a lot of knowledge through these.
Most of your advice would appear logical and intelligent and implementing some of these ideas has solved some occasional issues for me.
With regard to the Rosette Hack, possibly aptly named, it has worked for me and I only installed it on the suggestion from an Apple Guru.
However: I have read earlier posts and I am of the opinion that this procedure could possibly result in long term issues and have considered using the dual boot system.
Now; In your opinion, is it better to put say; 10.7, 10.8 and 10.10, which I have bootable OS masters of; on a partitioned single HD or on separate external HD's. I have several of these each of large capacity.
My thinking tells me, separate ext, HD's.
Thanking you in advance.

Sep 29, 2015 5:26 PM in response to The Art Of Soundby The Art Of Sound,That's a good question....
My opinion and experience is... Partitioning a Hard Drive tends to reduces it's overall performance (To more or lesser degrees depending on if you are accessing more than one partition at the same time or not..) so I try not to partition drives these days. Again, because the cost of drives has dropped.. I'd rather leave them unpartitioned and get max performance out of the drive than save a few bucks...
So, to answer your question... I'd use separate HDs which is, in fact, what I do here... so I can test things under different OS versions quickly and easily without disrupting my main stable system drives on the various Macs i have... and keeping the ext drives running at optimal speeds.
Hope that helps?
Cheers..
Nigel
