Why graphics card on Windows7 doesn't work like Mac OS?

I have broplem with graphics card on my Macbook Pro mid 2012. When I run Design Application on Mac OS It run very good graphics, but when I run it on bootcamp WINDOWS 7 it work so bad, could you please tell me about this ? And why Dedicated Video Memory show only 64MB on WINDOW 7 but MAC OS 512MB? Sorry for my bad English. Thank in advance.

Running Windows in a VM has nothing to do with running Windows in a Boot Camp partition on the Native hardware.
Your VM problem is in no way related as the VM software Virtual Machine controls what and how the graphics system works. It does not address the real native graphics hardware.
Yes if anyone Needs to Use Windows as there main OS it would be best to buy a Real Windows PC as Apple still limits what you can do in Windows and the hardware it uses on the Mac when installed in a BC partition.

Graphic card driver update doesn't work for Windows 8.1 upgrade (Ideapad Y500)

I upgraded my windows 8 to Windows 8.1 today and it probably is a huge mistake. After the upgrade my Ideapad Y500 started to look weird (Firefox stopped working). I searched around for solution and was told that I probably need to upgrade the driver to my graphic card. So I went to the driver download page and downloaded the NVIDIA GeForce GT750M Second VGA BIOS Update for Windows 8.1
I followed the instruction to run the "Winflash_Yx00s.bat" file, but after I seleted "yes" to let it modify the system, there is a very fast flashing a little black window (too fast for me to see what it is), and nothing happens afterwards. I checked to make sure that nothing is running in the background. After waited for half an hour I tried to restart the computer and still nothing happens. The display still looks weird.
Please help me!

¿Why sms and cell calls doesn't work on mac?

I downloaded iOS 8.1 and have yosemite OS installed in my mac. i have tried to use the calls and sms feature but none of this works.
In the calls when i try to call someone a message pops up saying that i must have an iphone and a mac with the same iCloud and FaceTime account. But the devices that i'm using do have the same accounts and still does't work!!
I have noticed that my phone number does't appear with a check and that in the FaceTime of my iphone a message down the switch to activates says "waiting for activation", but i can still make normal FaceTime calls. does this have something to do? how do i fix it? i have tried to reset the settings but everything is still the same.
In the sms feature the same message "waiting for activation" is down the iMessage title, i can send iMessages but when i try to activate sms a message says "enter the code displayed on the other device" but the code in my mac never shows up. What's the problem here? i have also tried to reset the settings and rebooting the devices but it's the same. Does this has to do with my phone number being unchecked? the problem is that i can't check it, the opti
Please help me.

Hello...
The SMS Relay and Phone Calls only work with a Mac device with Bluetooth 4.0 and later. If you want to see if your device has this, click on the Apple menu in the Menu Bar and choose About this Mac. A window then comes up with device information. Click System Report. On the sidebar, choose Bluetooth. At the top of the window it says Apple Bluetooth Software Version. If the number next to it is less than 4.0, your Mac device is too old. If it is above 4.0, your internet connection may have problems. Also if it says No next to Handoff supported, one of the devices is too old.
Good luck

Account doesn't work on Mac Mail but does on iPhone

I have a IMAP email account with my company that works on my iPhone and in Entourage but doesn't work in Mac Mail. I have tried to copy the settings and even did a full erase and reinstall of Leopard and no one has an idea why it won't work, the hosting company or Pro Care. Any idea out there?

No idea what "My apple ID account doesn't work on my itunes but it does on the web" means.
Please explain

HT204088 If I buy an app, and it doesn't work like its suppose to, can I get a refund, ?

If I buy an app that doesn't work like it is suppose to, can I get the $6.99 refunded back to my iTunes account ?

If you've tried contacting the developer and not had a response then you can try the 'report a problem' link from your purchase history : log into your account on your computer's iTunes via Store > View My Account (Store > View My Apple ID on iTunes 11) and you should then see a Purchase History section with a 'see all' link to the right of it ; click on that and you should see a list of your purchases ; find that app and click the arrow to the left of it, click the 'Report a Problem' link and fill in details about the problem (iTunes support should reply within, I think, about 24 hours).
Some people have had a problem with the 'report a problem' link (it's been taking people to this site on a browser instead of showing a form in iTunes) - if it does that to you then try contacting iTunes support via this page : http://www.apple.com/support/itunes/contact/- click on Contact iTunes Store Support on the right-hand side of the page.

IPhone 5 doesn't work with Mac OS 10.5.8 - do I need to ugrade to 10.6 and then upgrade to Mountain Lion or can I just upgrade to Mtn Lion right away?

iPhone 5 doesn't work with Mac OS 10.5.8 - do I need to ugrade to 10.6 and then upgrade to Mountain Lion or can I just upgrade to Mtn Lion right away?

At least to 10.6.8. You must do this to upgrade to Mountain Lion.
Upgrading to Snow Leopard
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s iCloud services; fees and
           terms apply.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion - System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later

[BUG]: MakeWritable doesn't work for mac

I'm trying to use oracle.jdeveloper.refactoring.util.MakeWritableHelper in my plugin, and I found it doesn't work for MAC. The byte code shows it only check the osname for "Windows" and "Linux".
and some Jdeveloper refactoring feature failed due to can't make file writable, they may also related to this class.

My MAC version is OSX 10.5.4.
I don't have a stacktrace. It just fails silently.
You can easily reproduce this bug by reformat a readonly file.
Here is the code I reverse engineered from oracle.jdeveloper.refactoring.util.Util.java:
public static boolean setReadOnly(java.net.URL url, boolean readOnly)
boolean ret = false;
java.lang.String cmdarray[] = null;
java.lang.String platformPathName = oracle.ide.net.URLFileSystem.getPlatformPathName(url);
java.lang.String osName = java.lang.System.getProperty("os.name", "");
if(osName.startsWith("Windows"))
cmdarray = (new java.lang.String[] {
"ATTRIB", readOnly ? "+R" : "-R", (new StringBuilder()).append('"').append(platformPathName).append('"').toString()
else
if(platformPathName.equalsIgnoreCase("Linux"))
cmdarray = (new java.lang.String[] {
"chmod", readOnly ? "u-w" : "u+w", (new StringBuilder()).append('"').append(platformPathName).append('"').toString()
if(cmdarray != null)
java.lang.Runtime runtime = java.lang.Runtime.getRuntime();
try
java.lang.Process process = runtime.exec(cmdarray);
if(process.waitFor() == 0)
ret = (new File(platformPathName)).canWrite();
if(ret)
oracle.ide.model.Node node = oracle.ide.model.NodeFactory.find(url);
if(node instanceof oracle.ide.model.TextNode)
oracle.ide.model.TextNode textNode = (oracle.ide.model.TextNode)node;
textNode.isReadOnly();
catch(java.io.IOException e)
e.printStackTrace();
catch(java.lang.InterruptedException e)
e.printStackTrace();
return ret;

Both Chrome and Safari interrupt online streaming to request/demand an update for a PC program that doesn't work on Macs. What is going on?

Both Chrome and Safari interrupt online streaming to request/demand an update for a PC program that doesn't work on Macs. What is going on?

The update alerts are fake, and are intended to dupe you into installing malware or disclosing private information so that your identity can be stolen.
You might get the alerts when visiting a website that has been hacked. Don't visit the site again. If applicable, notify the site administrator of the problem, but don't send email to an unknown party.
If you get the alerts when visiting more than one well-known website, such as Google, YouTube, or Facebook, then they're almost certainly the result of an attack on your router that has caused you to get false results from looking up the addresses of Internet servers. Requests sent to those sites are redirected to a server controlled by the attacker. It's possible, but less likely, that the DNS server used by your ISP has been attacked, but you should assume that the router is at fault until proven otherwise.
The router's documentation should tell you how to reset it to the factory default state. Usually there's a pinhole switch somewhere in the back. It may be labeled "RESET." Insert the end of a straightened paper clip or a similar tool and press the button inside for perhaps 15 seconds, or as long as the instructions specify.
After resetting the router, quit the web browser and relaunch it while holding down the shift key. From the Safari menu bar, select
Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. Do the equivalent if you use another browser. Open the Downloads folder and delete anything you don't recognize.
Then go through the router's initial setup procedure. I can't be specific, because it's different for every model. The key points are these:
1. Don't allow the router to be administered from the WAN (Internet) port, if it has that option. Most do.
2. Set a strong password to protect the router's settings: at least ten random upper- and lower-case letters and digits. Don't use the default password or any other that could be guessed. Save the password in your keychain. Any password that you can remember is weak.
3. If the router is wireless, or if you have a wireless access point on the network, use "WPA 2 Personal" security and set a different strong password to protect the network. If the router or access point doesn't support WPA 2, it's obsolete and must be replaced.
During the time the router was compromised, you were redirected to bogus websites. If you ever connected to a secure site and got a warning from your browser that the identity of the server could not be verified, and you dismissed that warning in order to log in, assume that your credentials for the site have been stolen and that the attacker has control of the account. This warning also applies to all websites on which you saw the fake update alerts.
Check the router manufacturer's website for a firmware update.
If you downloaded and installed what you thought was a software update, ask for instructions.
