• Can I connect my Mac Mini 2011 my end of 2014 Mac Mini using Thunderbold cable to double the RAM?

  My Mac Mini end of 2014 cannot add everything exceeds 8 GB RAM cable.

  I don't know why Mac was given the opportunity to add more RAM as applications become more and more wide and double my RAM will allow me to run applications of additional third party all in post processing my images.

  I have my Mac Mini 2011 with a Thunderbolt Plug and a delay in 2014 with 2 Sockets Thunderbolt

  I just want to connect two computers so that I can use 8 + 8 = 16 GB of RAM for photography post-processing.

  Buy everything just a Thunderbolt Apple cable to connect two computers and be speed up along?

  I'll probably have to update the old OS Mini at El Capitan

  Thank you!

  No. but you can connect both via TB for quick file sharing

• CS6 works with the AMD Radeon GPU 6970?

  I am currently using CS5.5 on a MacPro 1.1 version and given the CS6 upgrade that requires a 64-bit on Mac OS.  So I would get an iMac 27 ", but the GPU only offered are AMD Radeon 6770 M and 6970M, did someone at CS6 on iMac and how does it work?

  Thank you

  Well, it 'works' that she will support the fast previews and other features, it will not support just GPU raytracing. See the tech on the product page for AE.

• Mac mini el capitan "sleep next failure experienced a problem.

  I just bought a new mac mini with El Capitan installed, I transferred all my software and back up files on the old Mac mini via a time machine. Since then I've been finding this message once the computer has been idle: "sleep next failure experienced a problem. I click OK, the message disappears and everything seems to work, with the exception of the isight camera that I use a security system at home running on the imac. The problem seems to be Adobe Creative Suite related. Any ideas?

• Compatibility of AMD Radeon GPU has been removed in CS6?

  I was wondering...

  I checked the trial of the CS6 AE and noticed that I can not use my GPU in CS5.5, I was able to.

  I'm using an AMD Radeon HD 6950 2 GB and CS6 tells me the GPU is not available or has a device driver or incompatible display.

  I have the latest drivers for my graphics card so I don't think it's the latter.

  Compatibility of GPU AMD Radeon withdrawn in favour of NVIDIA or is the whole part of OpenGL of AE gone?

  Based on this Panel, everything was okay. You have no CUDA, which is normal, since it is NVidia only.

• Plus how is a Mac Mini in 2014 on a 2011 model?

  I'm in a quandry. I have an i5 to 2.3 GHz Mac Mini 2011. He needs a new hard drive. I use Photoshop to work. I think to put the cost of the hard drive to a 2014 2.6 GHz i7 Mac Mini.  This unit comes with a 1 TB hard drive, while I have the 500 GB drive in my current computer. How much faster and more responsive to the Mac Mini to 2014 will be compared to my 2011 model? It is worth the extra money? I'm buying a refurbished Apple to $589.

  Thank you!

  Bob

  You could put a fast SSD drive in your current computer, and he would make a big difference in performance. Alternatively, you can upgrade the RAM, unless you already have maxed out. $589 model has only 8 GB of RAM and the RAM cannot be upgraded, never. It is welded in place. Even a fast 7200 RPM drive spinning would improve the performance of your current Mini. The player stock 5400 RPM is a bottleneck.

  Photoshop like lots of free space. A big fast external disk would probably help also.

  If you have an Apple auhtorized service provider in your area, you could buy any player you want and pay to install for you, if you are not comfortable with the fact that yourself.

• Backup of two mac mini hard drives

  I have a Mac Mini 2011 with two 500 GB hard drives.  I have apps and General things about hard drive #1 and #2 only has pictures and videos.  Will be Time Machine backs up both drives to my external hard drive as one or two separate back ups?  I see files of backup HD #1, but not sure if the HD #2 files are also there.  I can't find an answer in the support documents.  Ideas?

• Mac Mini - no Ethernet Interface

  Hello

  I have the Mac Mini 2011 model, and I've been using an Ethernet for some time, have not had any problems, connection worked perfectly until now. First of all, there is no internet connection, so I have just connected to wifi for a bit, then I went into System Preferences - network, where more ethernet it indicated "cable disconnected" even if the cable is connected. I checked that the cable is not the issue, work on other devices. So I have that if I just remove the ethernet interface with - button, and then add it again with the + button that would solve the problem. However, now ethernet interface does not even upward in option:

  

  I'm currently under OS X El Capitan 10.11.3.

  Please help resolve this annoying problem, because the ethernet port is the key for the speeds for me.

  Thanks in advance!

• Mac mini mid-2011 show AMD radeon 6630 m

  I got a used mac mini. Works fine except; randomly breaks the display.  After countless times of restart, reset, hard reset etc, I found reconnect the HDMI cable kind of fix it.

  The display is Samsung s27d360

  I tried HDMI to HDMI, HDMI-Thunderbolt, VGA to lightning. So far, best seems to be HDMI-HDMI cable.

  I ran a complete test of the material (by pressing D on startup), no problems were detected.

  The monitor works fine with a cable on Macbook air 2012 configuration

  I got this blue screen after reboot before the login screen

  I also had once after the login screen

  I randomly get screen dividing / break in two

  Randomly get the grey screen with vertical bars (no pink or green bars)

  What is the monitor? Cables? (They are not original Apple) Firmware? GPU? I really want to continue to use it.

  I hope that someone had similar problems and was able to simply fix in an update of the firmware or display setting or a cable or something. Help please.

  Thank you

• Mid 2011 Mac Mini running slow/a lot of balloons of beach/HDD to research and writing

  I have a Mid 2011 Mac Mini, which runs slower than a snail's pace.  I frequently get beach balls as I type this message.  Startup time is very long, and the hard drive is often written / search/access for several minutes at random throughout the day.

  This seemed to start after I have updated to El Capitan 10.11.6.  I decided a few weeks to reinstall OS X without doing a thorough cleaning.  It did not help the situation, so I then proceeded to install the latest beta of Mac OS 10.12 to see if that helped.  Nope.  I don't think I have a bad hard drive, either.

  I have just run an EtreCheck and copied below.  Any ideas?  I don't want to run my computer at the Apple store.  Thank you!

• By the end of 2011 MacBook Pro, AMD Radeon HD 6770 M and CS6

  I just bought a second hand MacBook Pro (late 2011, i7 Quad 2.5 GHz with the 1 GB AMD Radeon HD 6770 M card) for a decent price. Here's the thing tho, I didn't know that AE CS6 does not play nice nice with AMD cards due because of the support CUDAGPU acceleration. Barefeats stipulates that ' every Mac with an NVIDIA GPU blew the...» AMD GPU... »

  So, having said that, have I made a serious mistake by buying this machine? I looked online but couldn't get a clear answer: will be AE CS6 performs well with my AMD card?

  Please note that I do not very big, but I need a kind of performance when I need (with out going into long explanations, I bought this machine to work at home, but I have a MacPro to work for the heavy stuff). What worries me is if I try and return, I'll sit for hours.

  Can someone let me know if the AMD card will limit my performance with AE (and PS, I) CS6?

• Allowing the AMD Radeon R9 M370X (MacBook Pro mid-2015) for accelerating GPU on Adobe Premiere Pro and other

  Hi all

  I just "upgraded" my MacBook Pro to a model of end of 2013 with a NVIDIA GeForce GT 750 M to a whole new model mid-2015 with an AMD Radeon R9 M370X.

  To compare performance, configure queues of same rendering with Premiere Pro Media Encoder in four sequences. These sequences contained native 4 K XAVC I, but four sequences have been "cropped" on a chronology of 25 1080 p, which means that I actually not export 4 K images. All four were slightly different, but while a 50 minutes.

  As I wanted to get an example of 'real world', I left on the old machine as CUDA rendering engine, as it's the best performance I can get the machine and the rendering engine on the new machine that OpenCL.

  I have to fill out a similar task at least once a week, so I know by experience, a queue of rendering as it takes about 2 hours by sequence to return.

  The results were very interesting and a little tell-satisfactory. Essentially, render on the CUDA compatible machine times were about 30% faster through all sequences of four compared to the AMD powered machine.

  Perhaps, somewhat lengthy explanation, but basically, I would like to know how to activate the acceleration in Adobe CC GPU - but especially with Premiere Pro, After Effects and Media Encoder.

  Apple seem to think that they support OpenCL (https://support.apple.com/en-us/HT202823), AMD announce their compatibility with Adobe CC (http://www.amd.com/en-us/solutions/software-partners/adobe) - then why my GPU does not appear as a recommended here model? - https://helpx.adobe.com/premiere-pro/system-requirements.html

  Any advice or suggestions are appreciated.

  Hey Connor,

  This R9 card comes out MAY 2015 and 2015 CC was released on June. So, any card (s) that is listed in Premiere Pro specifications list must pass appropriate tests. In addition, credit cards that has a 1 GB of VRAM is likely to allow "mercury Playback Engine" for use CUDA or open CL features.

  According to the rendering time is considered as MVidia GT 750 M has a priority on AMD R9 M370X. You can check and compare the two cards, and also check the link below.

• New Mac Pro, with dual AMD D500, GPU is not available?

  Is there something special I need to do to get the GPU to work in After Effects? Screen Information GPU said currently I Open GL, but the GPU is not available in the menu dropdown. In particular, I try to get the 3-d element performance, and I think that actually went slower than on my Mac Pro 2011.

  That's what chart using professionals are moving forward... Please tell me Adobe did not drop the ball on this one. He came out for almost a year!

  Element runs its own back-end stuff, all parameter of GPU in After Effects should not have an effect on how it works. Something is preparing for what is element.

  Like Rick, all uses of the AE the GPU for accelerates the ray-traced rendering engine, so I wouldn't worry at all. The inclusion of Cinema 4 d with your After Effects installation has made obsolete the raytraced render engine. In addition, speed up the rendering raytraced required engine cards NVIDIA, AMD not. This is why you cannot set to use your GPU; It's not NVIDIA. But, again, as I said, the ray-traced rendering engine is obsolete, if it's not quite relevant.
