  The it Department at my job have an image they put on work computers. We rent a new designer and they refuse to buy a new computer because they state that their image can be put on a new mac comes with El Capitan.

  If you ask if they can just roll back the OS X in Yosemite, they said that this could void the warranty on the machine. Does anyone know if it's done?

  You should not use an OS more old than what the computer shipped with.

  Some Mac 2015 could be able to run of Yosemite. For example, my early 2015 MBP retina came pre-installed with El Capitan, but with a Yosemite USB installer I was able to install Yosemite on it. It seems that you have an end 2015 iMac that maybe isn't able to run of Yosemite.

• After a clean install, Yosemite Mail crashes at launch

  I have re-installed Yosemite and upgrade 10.10.5 three days ago. Yesterday, I recreated 11 non-iCloud email accounts. I launched Mail and proceeded to uncheck the option "automatically detect and maintain the parameters" and to replace the port numbers incoming and outgoing according to the instructions of the ISP, I consulted in order to avoid the main Contacts and issues of mail in the course of the two months since my original Yosemite clean install - issues that have worsened to the point where I was advised in these forums to re - install. If I had known everything uncheck this option, perhaps none of these problems would be developed?

  After unchecking the option and change the port numbers for the incoming server and outgoing 11 IMAP accounts, I took all online accounts. Mail seems to be stable. I quit Mail and relaunched it five minutes later, just to be sure. He froze immediately on launch; There is not enough time to click on anything before spinning beachball appears and never goes away. I checked the Sys Prefs/Internet accounts: no problem.

  Here are the logs from Console for today attempted launch of Mail:

  If the problem is still there, try to start safe mode using your usual account.  Disconnect all devices except those necessary for the test. Shut down the computer and then put it up after a 10 second wait. Immediately after hearing the startup chime, hold down the SHIFT key and continue to hold it until the gray Apple icon and a progress bar appear. Startup is considerably slower than normal. This will reset some caches, forces a check for directory and disables all start-up and connection, among other things. When you restart normally, the initial restart may be slower than normal. If the system is operating normally, there may be 3rd party applications that pose a problem. Try to delete/disable the third-party applications after a reboot using the UN-Installer. For each disable/remove, you need to restart if you do them all at once.

• Cannot install Yosemite on iMac that accompanies a partitioned El Capitan

  Got a new iMac comes with El Capitan installed. Then, I created 3 partitions, who hold El Capitan, you hold Sierra and one I want installed Yosemite. Keep's message on installation of the software is too old for the machine. Tried the install app and disk image, no go.

  Thoughts?

  This message is correct. Yosemite does not have the drivers needed to start.

• Is there a compatible ssd to upgrade early 2015 Macbook Pro?

  Planning on buying a new macbook pro.  Information on upgrading the early 2015 macbook pro said that it wasn't something compatible yet.  I was wondering if in 2016 if anything compatible exist now?

  OWC (macsales) can have.

  But even open systems of the retina may void the warranty and can give the Genius Bar the right to deny any future service to avoid being blamed for what you broke.  Change the SSD guarantees you invalidation some.

• Backups Time Machine very slow on 2015 MacBook Air

  Associated with a topic of discussion between a few days ago (two MacBooks, 10.11.4, a fast Time Machine backup and a very slow), I start a new topic with new information that seem to show it is a problem more general and not related to Time Machine networks.

  Here's the situation:

  • A 2015 MacBook Air, 10.11.4, 8 GB / 512 GB, has extremely slow performance of backup Time Machine, taking 40 hours for the first 300 GB backup and incremental backups for a long time as well
  • TM performance is essentially the same whether on the network (wired Ethernet) or a USB3 external disk
  • When you back up to disk USB3, I confirmed that the information system shows that the port is configured as USB3, not USB2 (nothing else is plugged into the USB port)
  • Tests of bandwidth I/O gross (using dd and iperf) show no problem; the network reached 110 MB/s bandwidth, written network managed at 50 Mbps, external USB3 HD written work at 40-50 MB/s (write hard drive speed limit)
  • 3 other Macs of various ages from 2009-2014 on the same network have no problem at all do backups Time Machine Network; a backup complete first on a 2011 MacBook Pro 500 GB takes 5 hours or more than 10 x faster than the MBA problem
  • Time machine network uses a Linux server running the latest Debian and Netatalk 3.1.8 and the connection is via a USB3/Gigabit adapter, no WiFi, and iperf tests with this arrangement shows 900 MB/s of throughput of the server.  In all cases, the Time Machine and external time Machine Network USB HD have the same symptoms.
  • The problem with MacBook Air is configured the same as the MacBook Pro 2011, which she replaced "daily driver", possible
  • This problem was shown by the MBA since his unboxing conversion, taking 20 hours for his first backup once Setup initially.  Incremental backups now take several hours, leading to interrupted incremental backups and, I believe, databases corrupted backup triggers new full backups that take today the 40 hours.

  Using Terminal Server and iostat, Console, etc, I see that there is significant activity e/s for the backup drive on the order of 20 to 40 MB/s for long periods on the MBA during the TM backup, but during that time the average declared backup size as shown in the window in the console and TM is growing by only 5 GB/hour.  This occur even if the backup will the external drive or a network drive. This seems to mean that the I/O bandwidth to and from the disk hard external, only 1/600 contributes to the progress of the backup.  I am sure that there is overload of certain checks and other tasks, but not to a 600-to-1 ratio.

  I tried to disable the limitation of the I/O of low priority as shown here: http://apple.stackexchange.com/questions/212537/time-machine-ridiculously-slow-a close-el-capitan-upgrade, that helps a bit (maybe 20-30%), but not by a factor of 10 for others.

  I have gone through a number of the Time Machine of Pondini troubleshooting steps, but he found nothing corresponding to these symptoms.

  The only thing I can conclude is that Time Machine, the application or configuration, on this specific MBA, is down. (A single thought that I wrote this to the top that I have not tried: the MBA and the time MBP running VMware Fusion and have a file of 50 + GB VM; on the MBA that is not excluded from TM backups while on the MBP is)

  Does anyone have advice on what to watch next?  In all cases, only one key would be why it seems that only 0.16% of all the bandwidth I/O to the backup drive seems to be actual data backup.

  Once again, three other Macs, all running the same 10.11.4, back to the Time Machine Server perfectly and have for years.  Only this new MBA glue as broken out, either to a network drive or an external hard drive USB3.

  (A single thought that I wrote this to the top that I have not tried: the MBA and the time MBP running VMware Fusion and have a file of 50 + GB VM; on the MBA that is not excluded from TM backups while on the MBP is)

  What happens when you exclude it as the MBP?

  Assuming that you previously purchased on the app store and your Mac meets the minimum requirements, unload you enough data on an external drive to free the necessary disk space and update via the app store. If you buy before it and it is not in your shopping list, you do not have.
