On the same Mac?

 

I like to mess about installing different bits of software but sometimes removing it can be a pain and you can end up with all sorts of unwanted junk on there.

 

It occurred to me it might be nice to have 2 installs of OS X on the same machine - one nice and clean and the other as a sandpit environment.  And choose which to boot at startup.

 

Is this easy to do?  And is it covered with 1 OS X license?

 

Thanks

    Just create a partition on the internal drive, or use an external drive.

     

    If removing the software "can be a pain," don't install the software. If the software you try is not drag and drop (or App Store apps), make sure it comes with an uninstaller before you install. If it is so crappy that it doesn't come with an uninstaller (or at least explicitly clear and easy to use instructions), it is too crappy to try.

    Thanks for the reply.

     

    Unfortunately your advice about software would rule out most of the apps on the market, rendering them untryable.  The majority of apps I would suggest have no unistaller and leave crap all over the place if you simply drag the app to the trash.  9 times out of 10 I end up having to search for fragments, unused files, folders and library entries.  It will be whole load easier to try them out first in a sandpit.

    What "market" are you shopping? Almost everything I've seen has an uninstaller if it needs an installer.

    If it is drag-and-drop, you don't need an uninstaller as you just drag it to the trash.

    I can only disagree with you Barney.  I have all sorts of utilities and things - I will give you an example:

     

    BBC iPlayer Desktop

    Blackmagic Disk Speed Test

    Camptune X

    CCleaner

    ClipWrap

    Cyberduck

    Eizo-test_DEV_2.2.1

    Gimp

    HandBrake

    MakeMKV

    Max

    NoiseNinja

    Pure Music

    R-Studio

    Rember

    ScanSnap

    Scrambler

    Stellarium

    The Unarchiver

    Trim Enabler

    unetbootin

    VLC

     

    Most of them don't have uninstallers, and WILL leave crap all over the place if you just drag the app to the trash.  These are just some of the ones I have kept.  The deleted ones are probably worse!

    BBC iPlayer Desktop -- Requires Adobe Air = Crapware

    Blackmagic Disk Speed Test -- App store App. Just delete.

    Camptune X--no easy way to find uninstall instructions = crapware

    CCleaner--by definition, this is crapware

    ClipWrap-- App store App. Just delete.

    Cyberduck--Drag and drop app. Just drag to trash

    Eizo-test_DEV_2.2.1--Drag and drop

    Gimp--drag and drop

    HandBrake--drag and drop

    MakeMKV--drag and drop

    Max--not sure what this is. Found something related to Cycling 74 which is known to put out crapware that breaks at every os update; causes kernel panics

    NoiseNinja--drag and drop

    Pure Music--drag and drop

    R-Studio

    Rember--drag and drop

    ScanSnap

    Scrambler

    Stellarium

    The Unarchiver

    Trim Enabler

    unetbootin

    VLC--Drag and drop

    And I gave up on the rest as I have to go to work.

    Appreciate the time and effort Barney, but either you don't realise (or don't care) how much crap apps leave behind when you just remove them.

    Yes, your license will allow you to install Mac OS X on another partition, or disk drive.  You license allows you to install the OS on as many Macs as your own or control (does not include commercial users, just personal systems, such as the immediate members of your family).

     

    If you have Lion or Mountain Lion you can also install it in a Virtual Machine, such as VMware Fusion, Parallels, or VirtualBox where you can experiment without needing to reboot (note, you should have lots of RAM if using a virtual machine).

    You can do it with parallels I Know.

    Please check the SLA choosing Software/Mountain Lion (unfortunately, they've changed the format and copy/paste is just about impossible now):

     

    http://www.apple.com/legal/sla/

     

    Here is an excerpt from the OS license agreement:

     

    A. Preinstalled and Single-Copy Apple Software License

     

    Subject to the terms and conditions of this License, unless you obtained the Apple Software from the Mac App Store or under a volume license, maintenance or other written agreement from Apple, you are granted a limited, non- exclusive license to install, use and run one (1) copy of the Apple Software on a single Apple-branded computer at any one time. For example, these single-copy license terms apply to you if you obtained the Apple Software preinstalled on Apple-branded hardware.

    B. Mac App Store License

     

    If you obtained a license for the Apple Software from the Mac App Store, then subject to the terms and conditions of this License and as permitted by the Mac App Store Usage Rules set forth in the App Store Terms and Conditions (http://www.apple.com/legal/itunes/ww/) (“Usage Rules”), you are granted a limited, non-transferable, non-exclusive license: to download, install, use and run for personal, non-commercial use, one (1) copy of the Apple Software directly on each Apple-branded computer running OS X Lion or OS X Snow Leopard (“Mac Computer”) that you own or control

     

    Reading further, you can run 2 virtual copies of ML and you can install it on as many machines as you own and control, but there does appear to be a limit to one copy only per machine.

    Those listed as Drag and Drop or App Store, will leave behind a preference file and perhaps a folder in your user Library/Application Support/ folder. Neither of which will cause any problems, nor should take up much room, and are not difficult to remove if you feel you must.

     

    The only apps that will leave any more than that are those that are system modifications. They are installed with an installer which can put crap everywhere, but usually doesn't. These are the ones that you must understand how to uninstall before you install. If the Developer can't be bothered to easily provide an uninstaller, it is crapware, by my definition.
