Buggy Graphics on iMAC 21.5" 10.9.4
I currently(acquired it at the beginning of July 2014) own an iMAC 21.5" late 2013 model , having intel iris pro graphics card 2.7GHZ i5, 8GB RAM.
When I log in there is a delay in starting up and then when switching between desktops (I have 5 desktops) I notice the process is not smooth and the graphics are buggy(they seem to be distorted)! As if thats not enough, when scrolling through documents in Preview (7.0) and Safari (7.0.5) the text seem distorted and it really strains the eyes to read them! Also the same for other apps like ibooks(1.0.1).
I have done everything that I have read from various forums about the issues and still no success, until I realised that when I launch AutoCAD 2013, and start work on drawings, since I am a electrical engineering drafts man, the above problems all miraculously disappear or reduce significantly!
Which gets me wondering if the problem is with the graphics card or with the OS itself?
I would really appreciate some help since this is irritating as I have to open AutoCAD 2013, even when I am not using it for anything!
Thanks
Well, no one is replying to you so I'll just jump in here, although I'm no expert.
First of all there is this thread elsewhere: can i use 3dsmax 2015 on a mac via bootcamp
Second, I did run 3DS Max successfully on an iMac but that was several years ago on an older system so I don't know how current hardware and software will interact.
Thirdly, there are a number of threads here about how to install Windows on your iMac. Once you have Windows up and running you then install and run 3DS Max within Windows. To find out if your version of Max and your version of Windows are compatible you have to look at the system requirements for your version of 3DS Max which are available from Autodesk. Any questions about that are probably more suited to a 3DS Max forum.

Which is better graphic for iMac 2007 or MacBook Air 2012
iMac use ATI Radeon HD 2600 Pro 256 MB and MacBook Air use intel graphic 5000m so which is better?
Without knowing how you intend to use the computer it's impossible to say, also you are comparing apples and oranges.

I received an iBook as a gift. When I signed in to iBooks it asked for the password for my Apple ID. After I put this in I clicked on redeem. Asked for my Apple ID password again. Nothing happened. I clicked redeem again. It asked for my password once more. This was an endless cycle. I then redeemed the book on my iPhone and downloaded it without a problem. I opened iBooks on my iPad and also downloaded it there. Went back to my iMac (both at the time and also the next day) hoping I could now download it since all devices shared the same Apple ID. No luck. In preferences "synch across devices" was checked. I then also checked "automatic download." However, if I quit iBooks and restarted it, the automatic download was
now unchecked although synch was still checked. Also, if I closed the app and re-opened it I was asked for my password again. Since I don't do much reading directly from my computer, this is not a huge problem However, being obsessive, these kind of bugs really get into my head and are most annoying. Help would be greatly appreciated.You don't need to replace them unless you had books that weren't downloaded from the iBooks Store. In that case, restore from the backup you made.
Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2. -
Slow graphic transitions - iMac 2011 Mavericks
Few months ago I switched to Mavericks on my iMac 2011. (Few weeks in S.Leopard, than Lion, and directly to Mavericks)
It seemed all good but I am realizing that graphical transitions (such expose, widgets,... desktop change) are slow.. something like at a low frame rate.
I've also just noticed my iMac series (ending ... DHJW) has problems with the AMD Radeon HD 6970M 1024 MB and a replacement program is running.
However, I never experienced graphical problems with previous OS, so my graphical board should be ok.
Permission repair on hd didn't solve the issue..
Can you advice something before trying with a clean install?
additional infos: 12 GB ram, 3.4 GHz i7, 10.9.1 13B42 OS X, 27''.
many thanks in advance,
StevenIs AutoCAD installed?

Upgrading Graphics Card (iMac Late 2012)
I bought the new iMac 21.5" with the NVIDIA GeForce GT 650M graphics card with 512MB.
Is there any way of adding more memory or exchanging the graphics card?The NVIDIA GeForce GT 650M is a dedicated graphic card, so you can't add more VRAM to it. Also, the graphic card that the iMac has got is replaceable, but it can only be replaced by another graphic card of the same model. That's because only some graphic cards are compatible with OS X, and if you do this wrong, OS X may stop working or you may damage the logic board, apart from the fact that you will void the warranty. It's too risky and you won't have anything better than now. That graphic card is stable and should work for most of the uses

I'm going to be buy a new iMac today and I was leaning towards the base model with the Nvidia GeForce graphics. I see the next version up uses the ATI Radeon though and I'm wondering if it is a worthwhile upgrade for me.
This computer will mainly be used as a media server, but I do use it for video compression fairly often. Will a graphics card speed that up at all? I'm guessing no. I won't be playing any games on this machine. Otherwise some light video editing and Adobe Lightroom are also possible.The entry-level model you are looking at should do fine for what you want to do. I bought the 21.5" entry-level model, but upgraded the processor to 3.33Ghz and added another 4GB on third-party RAM for a total of 8GB. The 3.33Ghz processor has 6M L2 cache too compared to the 3.06Ghz's 3M L2. I'm real happy with this unit.

How would you go about improving your graphic card for an Imac. Would you have to bring it into an apple store?
You may be able to upgrade the graphics card but don't try to do this yourself.
Take your iMac to an Apple Store or Apple certified repair provider.

Slow graphics on iMac running 10.8.3
I recently installed Paraview on a new iMac with 10.8.3 and the graphics performance is slower than expected. Running the same software with the same data file on my older macbook pro laptop (running 10.7) resulted in better 3D graphics interaction, even though the graphics card on the iMac is better on paper. My laptop has an AMD Radeon HD 6770M with 1GB memory while the imac has "faster" NVIDIA GeForce GTX 680MX with 2GB memory. Has anyone else had issues with 3D graphics while running mountain lion (10.8)?
-JamesHi,
i have an iMac from 2012, and a Macbook Pro 13" from 2012 and, after upgrading to 10.8.3, i began to experience some poor graphic performance. When i switch between desktops it does it slower than before (wich it was excellent).
I have Mountain Lion 10.8.3 and i use my computer for graphic work (photoshop and similar), so it's a very annoying and notorius thing.
If anybody knows how to fix this, be my guest and thanks from now!

TableCellRenderer causes buggy graphics and is called again and again
I want to create a table with variable cell-hights, depending on the
number of lines that shall appear. This works by my following Renderer
(a JTextArea). But when I move my JDialog (or I also tried JFrame)
containing my JTable (inside of a scrollpane, of course) around, there
are still intermediate dialog-positions on the screen.
Another problem is, that the method getTableCellRendererComponent()
is called over and over again, as long as the dialog exists.
Here is the code of the Renderer:
private class MyTableRenderer extends JTextArea implements TableCellRenderer
public MyTableRenderer()
super();
setOpaque(true);
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)
Log.info("MyTableRenderer", "getTableCellRendererComponent() called");
String s = (String) value;
int count = 1, i;
if (s != null) {
for (i=0; i<s.length(); i++) {
if (s.charAt(i) == '\n')
count++;
table.setRowHeight(row, 17*count+4);
setText(s);
if (isSelected || hasFocus) {
setForeground(Color.white);
setBackground(Color.red);
} else {
setForeground(Color.black);
setBackground(Color.white);
return this;
private MyTableRenderer myRenderer = new MyTableRenderer();
Later in my dialog-constructor I do the following:
try {
Class cc = Class.forName("java.lang.String");
table.setDefaultRenderer(cc, myRenderer);
} catch (Exception e) {}
By the way: MyTableCellRenderer is a inner class of my dialog-class.
Please helpYes, you are right: The graphics is caused by the infinite loop
and the infinite loop is caused by setRowHeight().
To make sure it is called only once per row I intoduced a Hashtable rowHeights to store the old heights of earch row. setRowHeight() is
now only called, when there is nothing in the Hashtable for the
current row, or if the size of the Hashtable and the preferred size
(another improvement) are different. Here is the working code for my
Renderer:
private class MyTableRenderer extends JTextArea implements TableCellRenderer
Hashtable rowHeights = new Hashtable();
public MyTableRenderer()
super();
setLineWrap(true);
setWrapStyleWord(true);
setOpaque(true);
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)
Log.info("MyTableRenderer", "getTableCellRendererComponent() called: row="+row+", col="+column);
if (column == 0) {
String s = (String) value;
if (s != null && !s.equals("")) {
setText(s);
Integer oldHeight = (Integer) rowHeights.get(new Integer(row));
Integer newHeight = new Integer(/*17*count+4*/ getPreferredSize().height);
if (oldHeight == null || !oldHeight.equals(newHeight)) {
rowHeights.put(new Integer(row), newHeight);
table.setRowHeight(row, /*17*count+4*/ newHeight.intValue());
if (isSelected || hasFocus) {
setForeground(Color.white);
setBackground(Color.red);
} else {
setForeground(Color.black);
setBackground(Color.white);
return this;
Thanks a lot ! -
How do I make a background image come through the foreground?
If you mean by the following image effect:
Switch to layout mode
Place image in Pages and size accordingly
Duplicate the image (the duplicate becomes the foreground image)
Format menu > Image > Mask with Shape
Choose, or create the mask shape
Scale and position as appropriate
Click Done. Your duplicate is now inside this mask, and the original is now the background image.
You may wish to group background image and foreground image mask to retain position.
On the Pages v5 format panel, choose Image, and reduce opacity to fade the original image as desired.If you want this background image (or image and mask) on multiple pagesSelect image and mask. Arrange menu > Section Masters > Move Objects to Section Master -
Graphics Card Options on iMac 20 and 24 inch
I hate thelack of consumer graphics cards options for the iMac. I was going to buy the 20" iMac and upgrade the memory to 256MB when I decided to check out the 24".
On the Canadian site, to upgrade the 20" X1600 card to 256MB is $150. On the 24", to go from the Geforce 7300 128MB to the Geforce 7600 256MB is only $90. Ram 'AND' better(slightly?) graphics card upgrade.
Can someone explain as I asked an Apple retailer and they couldn't.
I went into CompuSmart afterwards and they actually had a X1600 card but it had 512MB on it. (For $150, I'd think I'd get an upgrade to 512, not 256).
I guess us consumers don't need more powerful graphics cards.
iMac Core2Duo Mac OS X (10.4.7)Let me see if I can explain this to you.
The grahics card in the iMac 20" is an ATI Radeon X1600. It comes standard with 128 MB of VRAM. You can upgrade the VRAM to 256 MB for $75 on the U.S. store. That's $150 on the Canadian store.
The standard graphics card in the 24" iMac is an NVIDIA GeForce 7300 GT with 128 MB of VRAM. The upgrade option here is not just adding more VRAM, but putting a whole new card in the iMac. The 256 MB VRAM option for the iMac 24" is a NVIDIA GeForce 7600 GT with 256 MB VRAM. That upgrade is $125 on the U.S. store. That's $90 on the Canadian store.
The only way I can think that this is possible is because, in Canada, ATI's cards might be more expensive than NVIDIA's cards.
There is no option on any iMac to get any graphics card with 512 MB of VRAM in it.
Hope this Helps -

Imac 24 aluminum with 750GB drive freezing
I have a new 24inch - 3GB 2.8GHZ and 750GB drive iMAC. I have 5 other C2D systems. The new one locks up from time to time - odd as the mouse moves but nothing else. have to remove power cord sometimes the button wont do it either.
I dont think its the drive - i have heard its the dog ATI video card that is doing it. The drivers are painfully slow compared to my other 24" prior generation 24inch imac with 7600 Nvida. not only are they slow it also looks like they are buggy. Why they would go to a slower and buggier graphics chip? Macs should be better in this area and this is a step backI had the same problem, I just purchased a new 2.8extreme 750gb iMac and it froze up on me!!
The mouse pointer would work and the dock would enlarge but could not select anything....
Now the scroll wheel(scroll down) has packed up on my wireless mouse....arrrghhh!!

Hello,
I need to buy a new Mac and my max budget is $2000.
I'm reading a lot about the new mac mini i7 dual-core processors, which are a lot slower than the late 2012 models and also slower than the iMac i5 quad-core model: http://cpuboss.com/cpus/Intel-Core-i7-4578U-vs-Intel-Core-i5-4570
I'm a programmer so I'll be using software like, photoshop, Xcode, VirtualBox, and some other related. I don't play games and I don't edit video, so from what I've read the new Intel Iris Graphics is enough. Am I right?
So I can choose from:
Mac Mini - $1400 (and plug two 24 monitors getting near my $2000 budget)
Intel Core i7 Dual‑Core 3,0 GHz (Turbo Boost till 3,5 GHz)
16 GB SDRAM LPDDR3 at 1600 MHz
1TB Fusion Drive
Intel Iris Graphics
OR
iMac 27" - $2100 (for this price, a little over my budget, I can choose from 16GB RAM or Fusion Drive, both costs $200 more)
Intel Core i5 quad-core 3,2 GHz, Turbo Boost till 3,6 GHz
16 GB de SDRAM DDR3 at 1600 MHz - 2x 8 GB
1Tb Serial ATA 1 TB at 7200 rpm
NVIDIA GeForce GT 755M 1GB GDDR5
I'm more into the Mac Mini, because I can have two 24" monitors (not as good as the iMac monitor of course) and take advantage og both 16GB RAM and Fusion Drive.
In the other hand, iMac has a pretty good monitor and a better CPu (video card is also better but like I said I'm not into games and video editing).
Also iMac will probably see it's new model this year while the Mac Mini was launched recently.
Based on all this info, please help me choose which will fulfill my needs better, fundamenting your choice.
Thanks a lot!I am an electrical engineer and do a lot of embedded firmware design
and supporting software, mostly in Win8.1 virtual machine with Parallels.
I also do a lot with Photoshop CS6 and some video work.
When confronted with an upgrade decision, I ended up going with the 27" iMac
and was glad I did. Expanded it to the full 32GB and am using an SSD via Thunderbolt,
I already had a Thunderbolt display, so I ended up with a very good workstation setup.
With that 32GB of RAM, I am able to have OS X, a Win8.1 coding/debug virtual machine,
and a Win7 software test platform all running at the same time and no noticable
performance hit.
Also, if developing large firmware/software, SSDs will speed the work up dramatically
as these types of projects are quite file intensive. The last project I was working on,
I could build, download and start debugging an embedded app using Win8.1 on a VM
before my coworkers were half way through building the app on their native Win laptops/desktops
which had standard had drives.
With that said, I still have 2 Minis in service. My 2011 Mini Server (my former workstation) was
repurposed to be my HTPC and my 2010 Mini has been re-assigned as my home iTunes/file server. -
We are ready to order a new iMac.
Of the options, which is the most important for Photoshop CS3/digital photography work:
A) the fastest video card, given two good choices
2.8GHz Intel Core 2 Duo or 3.06GHz Intel Core 2 Duo
B)the most powerful processor
ATI Radeon HD 2600 PRO w/256MB GDDR3 or ATI Radeon HD 2600 PRO w/256MB GDDR3
C) the most RAM
I've pretty much decided on the maximum 4 gigs of RAM, but am trying to figure out if I need the MOST in the other two departments. I am not a gamer, don't do video and am switching from PCs to Mac. Whereas I'd like to keep the price down, I do not want to be underpowered just to save a couple hundred bucks and have no one locally for a reality check.
Patti Neale>We are ready to order a new iMac. ...for Photoshop CS3/digital photography work
The latest iMacs will accept 4 GB RAM and have a FW800 port to add the necessary external drives. Today such a configuration indeed will do an adequate job of just running PSCS3 - but just running the apps does not make a box the best choice.
For life cycle and for performance reasons IMO iMacs are much less good choices than towers for desktop graphics workstations. iMacs are subject to the very significant limitations noted below.
Just the RAM limitation alone is an obvious serious limiter even with today's app versions, and as RAM prices continually fall modern apps and the OS are taking advantage of more and more RAM all the time. E.g. even though Photoshop can only directly address ~3 GB RAM, PS running under OS X has shown improved performance with 8 GB and more RAM for about 5 years now.
Boxes purchased today will be running the OSs/apps of the next few years, when the 4 GB limitation of iMacs will become even more significantly limiting. I consider RAM the bargain value performance enhancer today and it will only get better, so IMO limiting a graphics desktop box destined for 2009-2012 usage to 4 GB max RAM is poor life-cycle decision making.
I would also point out that, as consumer boxes, iMacs now only come with glossy displays. Matte vs. glossy is a matter of personal preference, but personally I find glossy unacceptable. Most graphics pros do not want their displays arbitrarily adding contrast and saturation to their work. That, for me, makes iMacs unacceptable at any price.
Some pros get around the iMac's glossy display issue by having their second display a matte and just using the iMac for palettes. I guess that could work but it is not something I would want to do because frequently I compare images on both displays.
All Photoshop versions require a separate hard drive for scratch to achieve best performance. That starts an iMac with at least one permanently attached external drive limited to FW speeds. The SATA of MPs is far preferable. Note too that if DSLR batch image handling were to creep into the usage during the life of the box that single FW800 port will also be limiting as regards disk i/o.
Any new box should be planned for the apps and OS versions expected to be in use during the life of the new box in addition to current apps. That includes CS4, OS 10.6 and beyond. And, IMO when buying for the graphics-pro future we should be equipping folks with the ability to handle image management apps like Aperture because managing DSLR captures will become more and more prevalent a need over the life of most new desktop graphics boxes.
iMacs are nice consumer boxes and I have purchased them for family members, but they are much less-good desktop choices for graphics professionals. Better would be a refurbished Mac Pro, even the 2006 model. Note also FWIW that new Macs of various flavors will be announced between now and Mac Expo SF in January, starting with laptops tomorrow (new MPs likely sometime between now and Q2 2009).
