MacBook Pro with 2 HDs and 2 Mac OS X installs, possible conflict?
I have just installed an SSD drive in replacement of my optical drive in my MacBook Pro. On the new drive, I did a fresh Mac OS X install and kept the old Mac OS X install on the old, original HD. I intend on formatting the old HD eventually, but I wanted to take my time to move files to the new HD manually.
I am experiencing issues with the fresh Mac OS X install on boot and only on boot. The new SSD drive has been selected as the default booting device.
On boot, I'll be greeted with either :
The prohibitory sign (circle with diagonal line), which will flash for a couple of seconds before booting Mac OS X from the old HD
A spinning wheel, which will turn for a couple of seconds before booting Mac OS X from the old HD
A spinning wheel, which will spin forever
If I boot in HD boot selection mode or whatever (holding Alt on boot), I am able to select the drive I wish to boot from and Mac OS X will boot flawlesly in a matter of seconds.
Is it possible that 2 Mac OS X installs on different HDs could cause such a conflict? Could formatting the old HD solve this issue?
Thank you!

Why can't I use my mid 2010 macbook pro with 8GB memoir and NVIDIA GEForce GT 330M 256MB to run 3D in photoshop CC?
3-D is very memory intensive.
System requirements | Photoshop
Mac OS
Multicore Intel processor with 64-bit support
Mac OS X v10.7, v10.8, or v10.9
2 GB of RAM (8 GB recommended)
3.2 GB of available hard-disk space for installation; additional free space required during installation (cannot install on a volume that uses a case-sensitive file system or on removable flash storage devices)
1024x768 display (1280x800 recommended) with 16-bit color and 512 MB of VRAM (1 GB recommended)**
OpenGL 2.0–capable system
Internet connection and registration are necessary for required software activation, membership validation, and access to online services.*
** 3D features are disabled and some Mercury Graphics Engine enhanced features may not work with less than 512 MB VRAM. Read the Help article.
Bottom line, you don't have enough VRAM

HT1338 hi what antivirus is best in macbook pro???and may mac pro is go slow?
hi what antivirus is best in macbook pro???and may mac pro is go slow?
Forget about viruses, and don't install Sophos, which is worthless.
First, back up all data immediately, as your boot drive might be failing.
One possible cause of a slow user interface is a large number of image or video files on the Desktop with preview icons. If you have more than a dozen or so such files, move them to another folder.
Otherwise, take these steps when you notice the problem.
Step 1
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 2
You must be logged in as an administrator to carry out this step.
Launch the Console application in the same way as above. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Post the 50 or so most recent messages in the log — the text, please, not a screenshot.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into a message.
Important: Some personal information, such as your name, may appear in the log. Edit it out before posting. -
I plan to buy a MacBook Pro with retina display and I already own and use Photoshop CS 5 on my PC?
I plan to buy and use a MacBook Pro with Retina display and I already own and use the PS CS 5 on my PC window-based. How can I obtain a copy of CS 5 for my MacBook Pro?
Message was edited by: CHARNCHAN. That is without having to buy another copy for the Mac!Not sure why you'd want CS5 for your new Mac with Retina display.
Retina support was first added to Photoshop in CS6 version 13.0.3
http://blogs.adobe.com/jkost/2013/01/retina-display-support-and-photoshop-cs6.html
So, assuming you own standalone Photoshop CS5 (and you're running at least Windows 7 on your PC) then your best option - for optimal display on your Mac - might be to subscribe to the Photoshop Photography Program for $9.99/month
https://creative.adobe.com/plans/offer/photoshop+lightroom?sdid=KIHZP
Then you'll get Photoshop CC + Lightroom 5 + extras and you can run them both on your Mac and Windows (2 installs permitted regardless of operating system) for the same $9.99 monthly fee.
If you don't want to subscribe then your other option would be to buy a separate CS6 license for Mac (paying full price). -
I have a new MacBook Pro with Lion installed and I want to know if I can partition the HD so that I can install & run Snow Leopard OS 10.6.8?
Most likely won't run SL unless it's one that was released before Lion went public. Color SL gone from new Macs.

I updated my MacBook Pro with Mountain Lion and now it is slow in starting up and loads a number of probrams. How can I fix the problem?
Have you tried starting in Safe Mode and see if the slowness still occurs?
Restart holding the "shift" key.
(Expect it to take longer to start this way because it runs a directory check first.)
If this works look in System Preferences > Users & Groups > Login items and delete any third party login items (-), you can always add them back with the (+). Also look in /Library/Startup Items. Nothing is put in that folder by default, so anything in there is yours.
Reboot normally and test. -

Why my safari browser is not opening pdf files?I'm currently using the lat 2013 macbook pro with os mavericks and all my software is uptodate?
Back up all data.
If Adobe Reader or Acrobat is installed, there should be a setting in its preferences such as Display PDF in Browser. I don't use those applications myself, so I can't be more precise. Deselect that setting, if it's selected. Otherwise do as follows.
Triple-click anywhere in the line of text below on this page to select it, the copy the selected text to the Clipboard by pressing the key combination command-C:
/Library/Internet Plug-ins
In the Finder, select
Go ▹ Go to Folder
from the menu bar, or press the key combination shift-command-G. Paste into the text box that opens (command-V), then press return.
From the folder that opens, move to the Trash any items that have "Adobe" or “PDF” in the name. You may be prompted for your login password. Then quit and relaunch Safari, and test.
The "Silverlight" web plugin distributed by Microsoft can also interfere with PDF display in Safari, so you may need to remove it as well, if it's present. The same goes for a plugin called "iGetter," and perhaps others — I don't have a complete list.
If you still have the issue, repeat with this line:
~/Library/Internet Plug-ins
If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari again. -

Setting up macbook pro with garage band and a mixing desk. NEED HELP ASAP!!
Hi everybody i have an issue which has been an issue for some time now.
i have a Behringer XENYX1222fx mxing desk, and a new macbook pro with the software 10.6.2 i am also using Garage band 09. when using this i am trying to set up my bass guitar through the mixing desk and the DI box which connects through a usb to the mac.
i can not get a signal/level come through to the macbook on garage band. i am getting a signal through on the mixing desk but nothing at all on garage band.
can someone send me the instructions to set it up? is it in system preferences in the input and output i really dont know please can i have as many options as possible.
Many thanks
ScottScott, I can relate. It's happened to me too!
It's time to play signal chain detective.
First, are you sure you are getting output from your bass? Plug it into an amp and test. (Once I figured out that the battery in my bass had died. New battery: problem solved.)
Once you know you're getting a signal from the bass, then check to be sure the mixer is outputting the signal. Run the outputs from the mixer into an amp.
Once you know your bass and mixer are cooperating, then it is time to engage the interface.
Be sure the preferences for the input to recgonize the interface are set BOTH in GarageBand and the OS generally. The problem is that when you connect an interface, GarageBand will see it and ask if you want to use that or line in. Be sure the interface is selected. For the OS preferences, click on the Apple logo and go to system preferences.
Finally, you might ask a friend to bring over an Apple laptop to eliminate the possibility of something wrong with your MBP, or lug your gear to his or her house, and try it. (Just remember to leave with all the settings restored to how you found them.)
If you live within reach of an Apple store, you can go to the genius bar.
And if nothing works, you can pay for a call to Apple support, or perhaps the support line for the maker of your audio interface.
Good luck. I know it can be frustrating when you want to make music ad you are spending a lot of time horsing around with the technology.
