• Download from the App Store is super slow

  Okay, so I finally bit the bullet & buy Final Cut Pro.

  No small decision here in Australia where it costs $499.99.

  Thanks for this Apple, really loved it when you took the price of about $ 300 to $ 500 in a jump... anyhews...

  I bought & started download around 2 hours ago. I would have liked to have done a bump just in the download 3 GB almost by moment but no.... Download speed I only sucked toward the low 199MB & time is expected to be completed despite a reliable 30Mbps is 1 day and 12 hours.

  Seriously?

  And is progressing well... another 7 hours later & I have downloaded a huge 641MB of almost 3GB.

  Estimated completion time... 2 days, 11 hours.

  Apple... could you if he please wake up the night watchman & have him go kick your awake servers? It's just ridiculous for a major technology company.

• Slow download Mac App Store on Unifi?

  Hello

  I have a Macbook Pro 15 "mid 2012 with"

  El Capitan 10.11.6

  I7 Quad - core 2.3 GHz

  8 GB RAM

  512 MB Nvidia Geforce GT 650M

  Evo 850 500 GB SAMSUNG SSD

  Mac App store is pretty slow lately. I have a connection optical fiber Unifi 30Mbps (but speedtest he registered as 60Mbps http://www.bandwidthplace.com/results/579c6e073bf641.88824201-50624087.png).

  The problem is that it's very slow. I did everything I could to hang up:

  1. change the dns. fact.

  2 clear the dns cache. fact.

  3. set the certificate CRL off keychain. fact.

  4 restart the app store. fact.

  5 restart the computer. fact.

  6 change the router to 50 beacon interval. fact.

  7 reboot the router. fact.

  If only I have the IP or the domain name for the download address and ping it to I can know whether it is the latency time. If this is true, it is the fault of the ISP. I want to ping this address and solve this problem at the ISP.

  Restart your internet modem and restart the router again and your Mac then try the App store.

• Toshiba STOR. E basics 1 TB - extremely slow

  Hello

  I recently bought this Toshiba STOR. E basics 1 TB USB 3.0 HDTB110EK3BA and it's extremely slow, taking already about 48 h for a copy of less than 100 GB.
  I am formatting it Mac Os more and using a Mac Book Pro with USB3

  Why is this happening?

  Thank you
  BR / Javi

  Why data transfer is slow?
  Who knows there are several reasons for this, you will need to check some things just to get a response for this

  Fact is that this HARD drive supports the USB 3.0 standard.
  This means that the HARD disk works with USB 3.0 performance (~ 130 MB/s)

  Still is it HARD USB 3.0 drive needs more energy than the common USB 2.0 HDD.
  900mA needs of USB 3.0, USB 2.0 HARD drive must 500mA
  That is why its recommended to connect the HARD drive to two USB 2.0 ports using the USB Y cable.

  However the speed of data transmission can be limited to the laptop (chipset).
  Maybe your internal HARD drive provides more performance for transmitting data to the external HARD drive.

  I read some tests on this HARD drive, and many users got the great performance.
  With the help of USB 2.0 ports: 31.8 MB/sec in writing; 31.5 MB/s read
  using USB 3.0 ports: 105,45 MB/sec in writing; 108,89 MB/s read

  I recommend you install Disk as ATTO Benchmark tools to check performance using another computer.

• App Store problems not search results or slow download

  Since the update to 9.3.3 iOS App Store (East coast of United States for me) gave me a lot of problems and errors with the search for updates and installation of applications. App detail pages also not load. What a coincidence, the update iOS or something else? -I can't even this post to the correct community (grayed out).

  Try a simple Reset: hold down the Home and Power buttons until you see the Apple logo (10 to 20 seconds).

• Download of virtual machine using extremely slow browser data store

  Hello

  Why download VM files totalling nearly only 8 GB in vSphere Client v4.1.0 (from 4.1.0 ESXi) via a Gigabit LAN would take more than 1800 minutes (30 hours)? Well now after about 5-10 minutes to download, it is said 1560 minutes but still, why is it so slow? I thought that perhaps is that the estimated time remaining is miscalculated, but this isn't the case. The download is just extremely slow.

  Not only that but vSphere Client (VpxClient.exe) constantly uses 25-45% of my cycles while all CPU's do the downloading of files. This slows down the PC I am running vSphere Client. The local network on the server and the client connections are Gigabit too.

  UPDATE: download time now has increased up to 1924 minutes back and it becomes difficult to use my PC for e-mail in Outlook, etc. because vSphere Client seems to use as many cycles CPU.

  UPDATE 2: 2 hours for download via vSphere Client and remaining time jumped up to 2287 minutes. I'm going to cancel and try to download via the web browser interface.

  See the attached screenshots.

  Thank you

  Derek

• How downgrade to El Capitan without having in the Mac App Store

  Hello! I'm completely new to Mac and for this forum. Coming from Windows, I found the keyboard a bit confusing. So I installed carabiner, which most of the time worked like a charm.

  Then there was a notification update to Mac OS Sierra. So I did. And now the carabiner is broken. In addition, the trackpad scroll is annoyingly slow, and I realized that I just liked El Capitan more generally.

  But since I got the Mac with El Capitan, I don't have in my list of purchased on the App Store. So where can I find an official download to create installation media, and then reinstall El Capitan (which, as far as I KNOW, is the only way to "downgrade" a Mac if I have no backup of before)? I have no personal files on Mac yet, so I don't mind erase the drive.

  Suggestions would be highly appreciated, even with solutions) 1 carabiner to work again and 2) to change the sensitivity of scrolling to the trackpad.

  Thank you for helping a newbie to Mac!

  Download El Capitan on the App Store

• Unable to download from the app store 10.6.8

  My main workstation (iMac) has worked so slow, that I decided to dust off my old Mac pro. I had forgotten how fast he is, or maybe I just took the habit to work on my iMac incredibly slow! Anyway, the only problem with my Mac pro is that I am on OS 10.6.8 - make my impossible navigation / insecurity. But when I visit the app store to upgrade my system I can't download anything at all. I click on the 'get' button and nothing.
  Of course I restarted several times, I activate the debug mode on the app store, I emptied the cache and reset the app store through the menu debug, disconnected and once again, rebooted again... still nothing. I even created a new apple ID to try as I was running out of ideas.searched these forums (and others) and I can only find stuff related to an Apple discussed with their servers, all these threads are now quite old so I guess that these issues have been fixed?

  Recently, someone at - he had this problem and solved it?

  If your MacPro is a 2006 model or 2007, you can't update to El Capitan.

  You can always buy codes redemtion for download Lion and Mountain Lion from the Apple Store online, not from the App Store, but these no longer receive security updates.

  If your MacPro is a model of the 2008,2009 and 2010, you should be able to upgrade to El Capitan via the App Store.

  On 20 September, Apple will release Mac OS Sierra, El Capitan will become more than likely unavailable.

  and only the 2010 model and later will be able to upgrade to the new operating system.

  You should consider upgrading the RAM in your Mac.

  There seems to be something wrong with your Wacom software. Uninstall it and see if that clears up the problem.

  The new App Store for El Capitan update has locked up my macbook pro.  Reboot got about 3/4 fact and the machine stops. Turned off the power and turn it on again for nothing doesn't.  How in my machine to begin troubleshooting?

  The problem is most likely an attempt to update a system malfunction prior it is probably a problem with your computer, not the El Capitan.

  Start by:

  Reset the PRAM and NVRAM on your Mac.

  MacIntel: Reset of the controller (SMC) system management

  Start in Safe Mode , and then re - start normally. It's slower that a normal start, so be patient.

  If you are unable to start;

  Reinstall El Capitan without erasing the drive

  Please make sure that you back up.

  1. Restart the computer. Immediately after that the chime hold down the command and R until the Utility Menu appears.
  2. Select disk utility, then click on the continue button.
  3. Select the withdrawal (usually Macintosh HD) entry of the volume in the list aside.
  4. Click first aid icon in the toolbar. Wait until the button is active, then click it.
  5. Quit disk utility and re-enter the Utility Menu.
  6. Select Reinstall OS X and click on the continue button.

  Also, see this tip for user: basic steps for the OS X upgrade.

  If this doesn't get you;
