Should I upgrade to OS 10.10 Yosemite from 10.85 on a Mac Mini 2009 (2.53Mhz 2duo, 4M 500HD) ?

Hi ... I asked this question a few months back ... and I received a few "yes you should" answers but I felt there was not much evidence to support recommendation ... but I am hoping that more people have had a chance to experience the OS on a low powered machine.  I have a Mac mini 2009 (2.53Mhz , 500 hard drive and 4 gig memory).  The mini is currently very happy with 10.8.5 (but I have yet to transfer all my media over from my Mini 1.6Mhz running 10.6) .
So will I see a performance drop if I install the free 10.10 upgrade ?
Many thanks

I would recommend installing to a fast external disk as a test if you are so concerned. Also keep a backup when/ if you upgrade & then you have little to lose.
Just be aware that iCloud can get updated for iCloud drive, which will lock older OS's out of that feature, so opt out if you are not sure.

    A Mid 2010 MacBook Pro supports 16 GB of memory without any problem. Macs are "special" about memory because some brands work without any problem and others don't work. That's why I recommend you to buy the memory from OWC or Crucial in order to make sure that you get compatible memory > http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade/DDR3

  • Upgrading from Panther to Tiger on Mac Mini 1.42 G4

    Hi Everyone,
    Would it be a simple install to upgrade a Mac Mini 1.42 G4 that I bought used and haven't yet turned on from 10.3 Panther (pre-installed by previous owner; also have discs) to OS X Tiger 10.4.6 that I bought new from retail store?
    I don't have anything on this mini to back up--no iTunes, no address book, plug-ins, 3rd party software, iPhoto--nothing. Can I just do a simple install?
    1.5 GHz PowerPC G4   Mac OS X (10.4.8)   Mac Mini 1.42 G4 (10.3.9)

    Although you certainly can do an upgrade install without erasing the hard drive, but if you do you should follow this procedure:
    1. Boot from the Tiger DVD.
    2. After selecting your language select Disk Utility from the Utilities menu of the installer.
    3. Select your startup volume from the left side list, then click on the First Aid tab in the DU main window.
    4. Click on the Repair Disk button. If any errors are reported as fixed re-run Repair Disk until no errors are reported. Then click on the Repair Permissions button and wait for permissions to be repaired.
    5. Quit DU and return to the installer.
    6. Proceed with the installation. When you get to the screen where you select the target disk select the disk and click on the Options button.
    7. Select the Upgrade option and click on the OK button.
    8. Continue with the installation.
    Because you have nothing to preserve on the drive I would recommend that you do an Erase and Install instead of the Upgrade install. There are some benefits to be had by not upgrading because some components of Tiger will not be installed during an Upgrade that are installed during a Clean Install.

  • Does Yosemite 10.10.3 now enable Mac Mini 2014 to drive 4K SST displays at 60z?

    Per Using 4K displays and Ultra HD TVs with your Mac - Apple Support update 10 APR 15, Apple indicates Yosemite 10.10.3 now enables the late 2014 Mac Mini to drive 4K SST displays @ 60z.  Several others on the web have said this isn't accurate.  Before I buy a new display, can someone clarify the situation?  Can this  software update enable the Mini to now drive these displays?  I thought it was a hardware issue.
    Thanks!

  • Can't upgrade to final version of Yosemite from the Developer Preview version 7

    So I have been running the developer preview of Yosemite on my Macbook Pro Retina all summer and have not really had any issues with it. However, now since the final release of Yosemite is out, I have not been able to upgrade to it. My computer is stuck on the Developer preview 7. The app store shows that it is updating like everyday, but when I try it manually it just says that it needs to "Show Details" and won't actually install anything. Then I tried to just click the download button on the Yosemite file in the app store, but it says that it is already installed. It says to press continue if I want to go ahead and install anyway, but there is no continue button. There is only a "Learn More" and "Ok" button. I'm not sure what to do at this point and really don't want to have to do a clean restart of anything. Any Ideas? Here are pictures of the issues I explained in the app store.

    I have the same problem. I've even tried to uninstall iTunes but I get the same errormessage that it can't find iTunes.msi. Specifically it says it can't find iToons 8.0.0.35. I can't get updates for iTunes or my iPhone.
    Is there any way to correct the problem? I'd like to uninstall it and reload it as long as I won't delete all of my music.

  • Should I upgrade my 2008 MacBook 5,1 from macosx 10.6.8 to 10.9.1

    I have an old 13" macbook 5,1 (first aluminium unibody model from 2008) with 4 GB of RAM and a 2.4 GHz Intel Core 2 Duo processor.
    Originally it shipped with Leopard (macosx 10.5), and I upgraded to Snow Leopard (macosx 10.6.8) in order to keep downloading security updates and for compatibility with newer 64 bit applications that only run on 10.6 and later OSs.
    However, concerned by possible performance penalties I did not switch to Lion (10.7) or Mountain Lion (10.8).
    Now the reviews about Mavericks make me think it might be a good idea to upgrade.
    The new features and eye-candy of the new version are of no importance to me.
    However the upgrade may reportedly improve system performance, at least w.r.t. Lion and Mountain Lion on relatively new hardware.
    What about older, barely acceptable hardware.
    My question is:
    * is there a good reason for upgrading my old hardware to mavericks? My priorities are:
      - system performance
      - security updates
      - compatibility with security updates of installed applications
    * my hardware is barely acceptable for an upgrade: is the upgrade likely to improve the system performance or the opposite?
    * until now I have never felt the need to upgrade: all applications I use still work fine with 10.6, with updates still supporting 10.6
    * however if security updates of the system or installed applications start dropping 10.6 I may be forced to switch to mavericks. Is this likely to happen anytime soon?
    Thank you for your help!
    best regards,
    uxl2

    If my experience with a similarly aged computer is any indicator, you'll notice an immediately speed hit once you've upgraded to Mavericks. Each OS X update tends to be more memory hungry than the previous and my 2007 iMac wasn't happy with Lion until I upgraded the RAM and at that point Lion performance roughly matched Snow Leopard. Mountain Lion and then Mavericks shaved some speed off again. Mavericks on the 2007 iMac was okay for the most part but switching between applications was slow as was the fileselector.
    My 2009 MBP saw similar slowdowns with Lion but I was above to upgrade it to 8GB which made a big difference. (My iMac was limited to 6GB) but I still saw a significant speed hit with Mt Lion when I tried to run multiple memory intensive applications. Seeing how my wife's MacBook Air dealt with Mt Lion with only 4GB I decided to install an SSD in the MBP and wow what a difference. Tried it with the iMac using a FireWire800 enclosure and saw similar improvement.
    So to boil it down to one sentence, you are going to see a significant speed hit with only 4GB but if you can afford to upgrade your drive to an SSD you'll be amazed at how well that computer can run.

  • Should I upgrade to the new os Mavericks from 10.6.8?

    So the reason I am still in os 10.6.8 is that I tried Lion when it first came out and I had 2 major issues.
    1. My mail which has an archive going back to 2006 was alllllll messed up.
    2. My occupation is using photoshop and suddenly photoshop was so slow i would draw a line and it would wait a second for the line to appear. I can't have that sort of slow down in my productivity. If it's ain't broke don't fix it, right?
    Well it was impossible to uninstall lion so I had to have techserv in NY wipe my computer and reinstall 10.6. ugh. Luckily I backed up but it was a wasted few days of work. Since this experience, I am sortof of the mind one should keep the program versions that were current when the computer was made if you don't want a computer that drags.
    My computer is a 12 inch laptop: 2.4 ghz intel core 2 duo, 4 gb 1067 MHz DDR3, (currently running 10.6.8)
    Short question, are the benifits of the operating stytem worth it or is this going to mess up my computer (specififcally in the ways mentioned above)?

    Hello,
    Only the Permissions keep getting messed up,
    You can ignore repeated Permission fixes if the last line says completed in it.
    See if the Disk is issuing any S.M.A.R.T errors in Disk Utility...
    http://support.apple.com/kb/PH7029
    Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
    How much RAM you have for real & free space do you have also, click on the Memory & Disk Usage Tabs.
    Open Console in Utilities & see if there are any clues or repeating messages when this happens.
    In the Memory tab of Activity Monitor, are there a lot of Pageouts?
    One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
    PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
    Reboot, test again.
    If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
    Check the System Preferences>Other Row, for 3rd party Pref Panes.
    Also look in these if they exist, some are invisible...

  • Trying to upgrade my OS to Yosemite from 10.6.8, but it doesn't want to work.

    I have to upgrade my operating system to Yosemite from 10.6.8. I've already checked to see what app compatibility problems I'll have to deal with, so I know pretty much what to expect. But when I go in to the Mac App Store and hit Upgrade Now, it sends me to a page that says Mac App Store Preview / OS X Yosemite. Then when I hit the View in Mac App Store button, it won't do anything, so I hit the link at the top of the page that says How to Upgrade, and it sends me to an instruction page that consists of a checklist of things to check on and the general requirements for the upgrade. Then when I hit the Upgrade Now button, it sends me back to that first Mac App Store Preview page that I was at before, with no way to get it to upgrade from there. If someone could please give me some advice as to how to go about this upgrade, I'd be extremely appreciative.

    It won't work the way you're trying to do it.
    Launch the App Store App on your Mac. You should see a search field along the top to the right. Key in Yosemite in the search field. From the resulting list you should see the OS X Yosemite Icon. Click the install/download button.
    Tips to try and make this as smooth as possible:
    Before doing anything do a backup of anything important - the whole system if possible. That way you can re-install if things don't work out - yes sometimes they don't. If connecting wirelessly try and make sure you're as close to the wireless access point (your router) as possible so as to maintain a good wireless connection; quit out of all applications; be patient, leave it alone and let it do what it has to do and follow any on-screen prompts.

  • Free upgrade to Yosemite from 10.6.8 - FAILED

    I've spent the last few hours trying to upgrade my iMac to Yosemite 10.10.2 (from 10.6.8), which I believe was do-able.
    URK - that's HOURS I'm never getting back - all for NOTHING - it FAILED TWICE.
    What is going on?

    When I upgraded to Yosemite this past weekend, on both my MacBook and iMac, I thought the upgrade failed because after an hour or so, all I got was a white screen with a thermometer half way - then everything stopped. I waited for over an hour on the MacBook (which I upgraded first).
    I was scared, and I was planning a trip to the Apple store. But I decided to force quit the MacBook by pressing and holding the power button. After it turned off, I waited a minute, then pressed the power button. It booted right up. I figure maybe a neutron lost its way and Yosemite just wasn't able to reboot my Mac. But I can see why some users would think the upgrade failed.
    So, I am wondering if this same situation happened to you, one in which the upgrade just stops AFTER it has been processed and is supposed to but doesn't startup.
    I upgraded 10.6.8-->Mavericks (6 months ago)-->Yosemite (this weekend). I don't know, but it seems to me you should be able to install directly to Yosemite from 10.6.8. Just wondering, but maybe you could try upgrading to Mavericks, then to Yosemite.
    As for your two hours of lost time you will never get back, well... welcome to the club. For some reason, you are in a minority of Apple users, as I have been, who have experiemced great frustration. As they say - there are two types of computer user, those that have been frustrated, and those who will be frustrated.
    Calm down, take it one step at a time. Answer the questions asked by those in the preceding posts. They will then help you.

  • Should I upgrade Intel Core Duo 1 Mac Mini (2006) to Snow Leopard?

    Okay I have a 80 GB Apple Mac Mini with Intel Core Duo 1 proccessor that shipped with Mac OS X Tiger (10.4.7) currently running 10.4.11 that I want to upgrade to either Leopard or Snow Leopard in a few months just in time for Christmas which I acquired in September 2006. It was the first Mac Mini model to include Apple's Front Row software and shipped with an Apple Remote (I know Macs don't ship with Apple Remotes anymore you have to buy them separately) and am now pondering an update. I've heard some things about Snow Leopard not working so well with older Macs even Intel based Macs that are only 32 bit.
    Thing is I just got a new MacBook Pro that shipped with Snow Leopard and it seems to run fine on the MacBook Pro except for the fact a few applications I wanted to install wouldn't work with Snow Leopard like Google Desktop for Mac so was wondering if I should update the Mac Mini also to Snow Leopard. I do not particularly like how Apple removed the transcoding features to export video from one format to another in QuickTime X that was available to QuickTime 7 Pro users (actually reinstalled QuickTime 7 Pro on my new MacBook Pro so I can still use that despite QuickTime X being installed) but like Expose integrated with the Dock Menu that's new in Snow Leopard and features like Cover Flow built into the Finder (available also in Leopard along with Spaces) so if I update the Mac Mini should I update to Snow Leopard or Leopard?
    This is a 2nd generation Mac Mini (the 1st generation had PowerPC chips) with Mac OS X Tiger and I've heard some negative news about upgrading Mac Mini to Snow Leopard so I want to get some more feedback on whether or not its worth it. The Mac Mini came with iLife and iWork 06 versions but updated iWork to iWork 08 Family Pack. Still have iLife 06 though and am still running iTunes 8.2.1 on the Mac Mini.
    I use this computer as my main system for syncing with iPods (I have a 5th gen video iPod and a 2nd gen iPod Touch that I sync with the iTunes Library on my Mac Mini which includes videos purchased earlier from iTunes Store and music purchases as well as TV purchases) so don't want to risk messing up the system with a Snow Leopard update if it is going to cause problems doing so. If Snow Leopard is not good for the Mac Mini will just update to Leopard and stick with Mac OS 10.5 Leopard on this system.

    I upgraded my mac mini 1.5GHz core solo to a Core 2 Duo 1.8Ghz in order to run most of SL's 64 bit stuff. I bought a pulled Core 2 Duo from ebay for $29 and it took about 1.5 hours to do the switch.
    The main downside with the 2nd gen Mac Mini is the kernel cannot run in 64 bit mode due to a 32 bit controller that cannot be upgraded. Yet, booting into 32 bit kernel is SL's default setting and as you may have read in articles when SL came out, relying on a 32 bit kernel does not slow down use of 64 bit apps. I maxed RAM to this mac mini's 2 Gig limit years ago which is a good thing for you to do too.
    I am happy to report the upgraded Mac Mini runs much faster than originally thanks to the 2 gig of RAM and the Core 2 Duo chip. Installing SL made it run faster still and consumption of memory for apps is lower (smaller pipeline requirements with faster CPU), and about 14 GIG of HDD space was recovered since I did not reinstall Xcode tools. I can now encode 1.5 hour long video files that used to take overnight processing time. CPU runs hotter, up to 89ºC, but usually run only about 10º higher on average than before while fan rev's not noticeably more than before between 1500 to 1800.
    If you are not comfortable to upgrade the CPU, I think you will still find some benefit to SL for $25. Alternatively you could sell your Mac Mini on ebay (these 2nd gen model are popular for those want to do the upgrade) and use the proceeds to buy a refurbished current gen Mac Mini.

  • Creating NetRestore Image of OS X Yosemite (10.10) from Mac Mini Server Running Mavericks (10.9)

    Hello all,
    We are attempting to create a NetRestore image of a Macbook Pro running Yosemite (10.10) from a Mavericks (10.9) Mac Mini running OS X Server. Previously we connected a Macbook Pro in target mode to our Mac Mini (both running Mavericks) using System Image Utility to create a NetRestore SP0 from which we could deploy to all of the computers in our lab running Mavericks. We did this as a method to update the applications on each iMac locally from the hosted NetRestore image we created. We are now receiving several new iMacs and Mac Pros running Yosemite (10.10) native and we wish to use the same process to update these machines from our Mac Mini (Mavericks) running OS X Server.
    We are now trying create a NetRestore image from a native Yosemite Macbook Pro using System Image Utility on our Mac Mini (running Mavericks) however when the Yosemite Macbook Pro is connected in target mode, System Image Utility does not recognize the volume although it is recognized by our Mac mini (e.g., the yellow-orange image icon is displayed on the Mac Mini's desktop). Some of our lab computers are still running Mavericks, and my understanding is that Mavericks NetRestore Images cannot be created from a Mac Mini with OS X Server running Yosemite.
    Must we upgrade our Mac mini from Mavericks to Yosemite for System Image Utility to recognize our Yosemite Macbook Pro (connected in target mode) in order to create a Yosemite NetRestore Image?
    Note: We know there are better alternatives (e.g., Munki) to deploy updates to our machines via server and are working to establish a more convenient process, but this is the method we have been comfortable using before running into the above issue.
    Thanks all!

    You could use DeployStudio to 'serve' both Yosemite and Mavericks images from your Mac mini which can still run Mavericks. You would also use DeployStudio to make an image of the MacBook once it has been loaded and then this image can be restored to multiple machines.
