Macbook sleeps with long delay and tons of system messages
It takes my MacBook Pro a long time to go to sleep (4 minutes or more). During this time thousands of messages are produced in the System log.
There are so many of them that some messages are discarded. Some of these messages:
05/10/2014 16:31:08.000 kernel[0]: [0x445334a000, 0x2000]

What do these messages mean?
I have tried, without success, the following things:
- reinstall the system
- perform a disk verification
- repair file permissions
- boot in safe mode
What I have not tried is a hardware check, because I couldn't. (Starting up with D pressed has no effect and starting up with option-D pressed initiates the check, but this is aborted because my machine doesn't support it.)
The behavior takes place with hibernation, not with "unsafe sleep".
Machine: MacBook Pro 15" mid-2014, 2.4 GHz Core i5, 8GB memory, with Mac OS 10.9.5.

Thanks for the tip. I checked out the link. The issue is not that my log files are large but it's that log messages (the same message over and over again) are being constantly written to that Console application - I guess by syslogd - at a crazy rate per second which is causing the CPU to spike and causing my Free RAM to go from say 3GB to a few MB's within a matter of seconds. I actually can't find a log file on my system (via Spotlight search or Terminal "grep" searching) that has the hundreds and thousands of messages showing up in the Console log app. syslogd just gets "crazy" and pretty much takes over the CPU and depletes my computer free RAM when handling those:

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. -
i buy a macbook air with my friend and i changed the apple id also.at first i can update the application but now its impossible to update the application.when i clock to update it shows the id of my fren andsomebody do you have idea to solve this problem.
The first thing to do with a second-hand computer is to erase the internal drive and install a clean copy of OS X. You — not the previous owner — must do that. How you do it depends on the model, and on whether you already own another Mac. If you're not sure of the model, enter the serial number on this page. Then find the model on this page to see what OS version was originally installed.
1. You don't own another Mac.
If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard (OS X 10.6) installation disc from the Apple Store or a reputable reseller — not from eBay or anything of the kind. If the machine has less than 1 GB of memory, you'll need to add more in order to install 10.6. Preferably, install as much memory as it can take, according to the technical specifications.
If the machine shipped with OS X 10.6, you need the installation media that came with it: gray installation discs, or a USB flash drive for some MacBook Air models. For early MBA models, you may need a USB optical drive or Remote Disc. You should have received the media from the previous owner, but if you didn't, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.
To boot from an optical disc or a flash drive, insert it, then reboot and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.
If the machine shipped with OS X 10.7 or later, you don't need media. It should boot into Internet Recovery mode when you hold down the key combination option-command-R at the startup chime. Release the keys when you see a spinning globe.
2. You do own another Mac.
If you already own another Mac that was upgraded in the App Store to the version of OS X that you want to install, and if the new Mac is compatible with it, then you can install it. Use Recovery Disk Assistant to create a bootable USB device and boot the new Mac from it by holding down the C key at the startup chime. Alternatively, if you have a Time Machine backup of OS X 10.7.3 or later on an external hard drive (not a Time Capsule or other network device), you can boot from that by holding down the option key and selecting it from the row of icons that appears. Note that if your other Mac was never upgraded in the App Store, you can't use this method.
Once booted in Recovery, launch Disk Utility and select the icon of the internal drive — not any of the volume icons nested beneath it. In the Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive.
After partitioning, quit Disk Utility and run the OS X Installer. You will need the Apple ID and password that you used to upgrade. When the installation is done, the system will automatically reboot into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.
Then run Software Update and install all available system updates from Apple. To upgrade to a major version of OS X newer than 10.6, get it from the Mac App Store. Note that you can't keep an upgraded version that was installed by the previous owner. He or she can't legally transfer it to you, and without the Apple ID you won't be able to update it in Software Update or reinstall, if that becomes necessary. The same goes for any App Store products that the previous owner installed — you have to repurchase them.
If the previous owner "accepted" the bundled iLife applications (iPhoto, iMovie, and Garage Band) in the App Store so that he or she could update them, then they're linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Apple customer service has sometimes issued redemption codes for these apps to second owners who asked.
If the previous owner didn't deauthorize the computer in the iTunes Store under his Apple ID, you wont be able to authorize it immediately under your ID. In that case, you'll either have to wait up to 90 days or contact iTunes Support. -
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

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). -

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. -
