Over the past year or so the Mac Pro Twin quad Core 3.z Gh Xeon 2008 had been gettin gmore and more cranky.


Sys prefs keeps crashing when starting, light room freezes, lots of other apps often freeze too, with the spining beach ball of death.  Once a week now or more I have to Press and Hold the power buttong as the whole system just locks, either in use or on shutdown.


Have Google'd the many and various problems tried many solution, all no good..Disk repairs and veryigy / permsiiosn ..deleting plists etc etc.


So looks like a complater reisntall is required.


ML does run on this machine, as I have isnstalled from disk on a partition on the Mac HD.


Machine has Four HDD. 


The users Home Folders stored on a seperate HDD



How do I go about this and keep ALL my Mail settings and folders etc.


Can I jsut stick in the ML disk and let it upgrade all or will there be a massive headache in getting mail sorted and transfered across?  When I did the previous ML install, it was a 'Standalone ' install on a seperate partition, and did not let it tinker with my Mail and user folders.


How do I go about this?

    Windows - Paragon Software: Clone OS, somewhat similar tol CCC only will only do a FULL partition copy (not "smart" update kind) and the ability to 'exclude' folders never worked for me (moving large HDD to small SSD).


    Going "up" from lower OS number with Mac 'should' in theory work with either Migration or Setup, but there are user account issues sometimes. Mail file index/database gets changed and altered, as does TimeMachine, no going back. Hence, the "dual boot" leave the old one alone as it is... just in case.


    But do have multiple redundant backups: TM, CCC (probably two here), and start wtih a FRESH Time Machine backup drive (pull the old one).


    Clean - the word - has gotten a lot of push back "we don't need to be like Windows" but there are (me) and others using CCC - and who format disk drives with the new OS. Even discussions of what the word "clean" means, believe it or not, we did, as if it was "Windows only" terminology or had no basis outside of.


    Pull the old drive. Make a clean break.


    I am not, would not, partition the same drive, no way. I would use a newly erased full drive and have Emergency Partition there also (and elsewhere, clone it and CCC will ask to create a 2nd Recovery Partition also, which Apple OS does not - they are a "once only").


    Unlike Windows you don't need to go through much in the way of reinstalling software and drivers though.


    The absence of Rosetta though strongly points to clean install to break with the past "cleanly."


    The only list or spreadsheet would be those tables from MacIntouch or RoaringApps as to what version is supported, what updates the new OS requires, which you might need to do. And by dual booting you still have the security and safety of going back.


    And going back so you have copy of Lion or Snow or even 10.8.3 until .4 has been working and you can update the clone too. Safety net. to play with or test.

    PowerPC code was still around with Intel Macs - Universal Binaries help but some programs and utilities also used Carbon code compilers.


    A clean install is easy, straight forward and less trouble.

    WE agree on a clean install. It is what you do afterwards that is extra... of course anything less than USB3 will be slow, even FW800 is slower.


    How safe it is to migrate or use data from your TimeMachine backup depends on quality of and redundant backups. Whch is why having more than one backup sets, having cloned your system from "back when" prior to any issues causing data or system issues.


    I like to see people take the cleain install, image it for safe keeping, then make any changes and test, but to go as long as possible before using MA or SA with a virgin system first. Creating a new user acccount is also another way to test and isolate issues.


    Windows Easy Transfer only restores user data, not applications which forces a more laborious reinstall of every driver and application - unles you have those on a non-system drive of course and just redirect the system to them.

    Problems  after  using  Migration  Assistant


    Apple even includes a version of Migration Assistant for coming from a Windows computer


    I never used or touched XP, which I guess is why it is hated so much, I went from CP/M and DOS (and yes there even was "DOS" back in the early days of IBM/360).


    I use Windows 7 and 8 and really they aren't that far different from OS X (and there are things OS X could learn from)

    iCloud and the others you mention, the iOS and iDevice, the iOSification if you will, do have a number of problems -- was why I held off on Lion until a couple apps I needed to use req'd 10.7.5 (I have not used ML and my Mac Pro cannot). Sort of reminds me of all the push-back of Microsoft pushing Metro into Windows 8 that users (on desktops at least) cannot stand. Next week I get to look at 8.1 and have to go silent.


    If there are installers, and there are for those that are not drag and drop anywhere, they have to have imperfect uninstallers and no central repository.


    I spent so much time on computers for work I never wanted one in the house. Maybe remote login so I didn't have to drive into work at night or weekends, sure, or during a snow storm, but Windows NT didn't sound promising... I was rooting for IBM's OS2/Warp, or IBM PC/370 /3270 (they were "ideas" and not intended to market but some found them facinating and worth $7,000 - my boss was flaburgasted at the $10,000 Apple offering!)
