MacBook Display Will Not 'Remember' Brightness

Okay, so I finally went out and bought a black one. Since the Core2 models came out, it came to me at a great price.
I'm very happy with it after a RAM upgrade to 2GB and after I turned down the screen brightness. The machine remembered my screen brightness setting until I applied the latest firmware update. Now every time I start (or restart) it, the screen comes on at nearly full brightness.
I find the full on brightness setting to be far too bright (and irritating) and possibly hard on the backlight. What can I do to fix this problem?

Thanks for the suggestion. However, I think that the
option you mentioned is only available on the Macbook
Pro. I have a black Macbook.
If you're referring to the following:
change the screen resolution to something else and back and reboot.
...then go to System Preferences, Displays and in OS X 10.4.8 you'll surely find an option to change the screen resolution (so: NOT only in the MBP).
Arjan.

Macbook Pro will not remember wireless network

We have two Macbook Pros and are having issues with one of them not finding and then not remembering a particular wireless network. The other one works normally on this network, as do our iPad and iPhones.
The problem Macbook Pro will find a number of other wireless networks in the vicinity, but not the one we wish to connect with. However, when the required information about the network is entered into the Network Preferences, it does see the network and will connect with it, until the computer is shut down. When it is powered-up again, the Macbook will not find it, even though, in theory, it had been told to remember it and that network had been moved up to #1 in the order of priority.
The settings on both Macbooks are the same, so why can one find and remember the network and the other not? What can I do about the problem?
Help please!

Settings for wireless network connections are actually stored in two separate places on your Mac, so in addition to the correct advice offered by Jolly Giant, you will also need to delete old network listings in KeyChain Access.
Macintosh HD > Applications > Utilities > KeyChain Access
Locate the name of the wireless network that you want to delete and click it to highlight it
Click Delete on your keyboard
It would be a good idea to go ahead and also delete the current connection as well in case it has become corrupted. This will clear out the old settings and when you next connect to the network and enter the password, the new settings will be preserved.

Macbook Pro will not power on the Display.

Just turned on my Macbook Pro, heard the powering-on chime, but the Display will not turn on. Battery is fully charged. I attempted the various restart options. Pulled out battery. Reset. Reset Pram. But still no display. Please help with any further tech support or trouble shooting steps.

I have had this sometimes - the screen goes black. When you turn the machine on, hold tap the "screen brightness" button a few times. (That'll be the button 3 in from the top left on the keyboard with the sun icon on it).

I have a MacBook Pro 15" 2.53GHz Mid2009.. updated to Lion which is now 10.7.3 build 11D50b... when I close lid and connect to Cinema Display, display will not activate... disconnect display, open lid laptop display will not activate... used to work fine.

I have a MacBook Pro 15" 2.53GHz Mid2009.. updated to Lion which is now 10.7.3 build 11D50b... when I close lid and connect to Cinema Display, display will not activate when keyboard/mouse used... disconnect display, open lid and laptop display will not activate... only way out is hold power button. Worked fine before Lion update. Any Advice?

Thanks very much Coander15... I've printed the doc you pointed me towards and I'll run through it.. hoping it helps!
Before I installed Lion I simply hit any key on the keyboard or clicked the mouse...
The keyboard is USB (usually connected to monitor which is connected to laptop... have tried direct connect to laptop as well with no luck) and mouse is USB wireless to one of those tiny plug in's... have tried direct connect USb mouse as well with no luck.
I could plug the closed/sleeping laptop into the monitor and unplug from the monitor without incident all day/night... always worked fine.
Had heard something about this happening w/ Lion but went ahead anyway.
Oh well...
Hoping your pointer helps... will let you know how it turns out. Thanks very much for responding!!!

Welcome to Apple's discussion groups.
I'll presume that you can adjust the brightness after bootup. If that display preference is kept in PRAM, it's possible that the PRAM battery is wearing out.
Here's what Apple says about what's stored in PRAM:
http://support.apple.com/kb/HT1242
To test that possibility, turn off "Set date and time automatically" in the Date & Time panel of System Preferences (if it's set), shut down and unplug your Mac, then let it sit for a few minutes. When you reboot it, check the system date and time. If the PRAM battery is failing, those may be set incorrectly.
iFixit describes replacing the PRAM battery of an iMac G5 as of "moderate" difficulty. See these pages:

Display will not sleep any more after waking from sleep

My Macbook has recently started misbehaving after waking from sleep. Started putting the entire MB to sleep each night by closing the lid. When I wake it in the morning everything seems normal, no error messages. However from that point forward the display will not dim or sleep. I've tried re-applying my settings in System Preferences -> Energy Saver. Pretty much the only fix has been to reboot, which is annoying and Windows-like.
In the interest of full disclosure, I have "fast sleep" enabled (aka hibernation mode disabled) but I've had that since I bought my MB with 10.5.1 on it. So I don't think it's related. In fact I changed to the default Energy Saver profile to see if that fixed the problem (it didn't), which re-enabled hibernation mode and I then had to re-disable hibernation.
I want to say this started happening after the 10.5.4 update, but that may have been a coincidence as to when I started sleeping it each night... I don't exactly remember.
I downloaded Cocktail to run all the cron jobs, etc, that don't get run when sleeping at night, and that didn't help either.
Any suggestions? Anyone else ever see this? Seeing it now?
Thanks!

This is still an issue for me.
I sleep my Macbook every night by closing the lid. After doing this a few times, the display either stops sleeping, or stops locking. I have the lock menu in the Apple menu bar, and even selecting "Lock screen" will not work.
Sometimes a reboot fixes it, sometimes I have to reset the SMC.
Any info out there?

Mid 2010 Macbook Pro will not stay off or asleep

Hi,
I have a mid 2010 MacBook Pro will not stay turned off when I tell it to shut down. It will shut down just fine, but a few seconds later it will boot up again. This also happens when I try to close the lid (or just put it to sleep), it will work fine, screen/Apple logo on the back will turn off and the status LED will slowly pulse. However a few seconds later, the LED stops pulsing and the Apple logo will illuminate. If I open the lid I will be greeted with the log in page with zero delay (i.e. its been displaying for a while).
This has become problematic because the computer always be running. If I put it in my laptop bag the computer will get hot as ****. The only way to get it to really turn off is to let the battery die or remove the battery. But this computer does not have the externally removable battery so that is not a trivial process.
The symptoms exist in both Mac OS (Mountain Lion and Maveriks) and Windows 8/8.1. This makes me believe its something in the hardware (or at least a setting in the hardware), not software (I know Apple doesn't care what Windows does, but it is exibiting identical behavior).
I have reset the NVRAM and the SMC with no luck. When I reset the SMC I didn't get a good indication that anything happened though, and was wondering if that is normal. Resetting the NVRAM results in another restart, while its hard to tell if you actually reset the SMC. I reset the SMC by turning the computer off, then holding the power button when it tries to restart (this usually gives me a few minutes where the computer will actually stay off), then pressing shift, control, option and power at the same time and releasing them at the same time. This is how the Apple documentation said to do it. They did not mention how long the must be held though so I presume that doesn't matter.
Anyone experience this/have any ideas?
Thanks,
Jim

The MacBook Pro will not allow me to cut-and-paste to and from or to click-and-drag to the external drive. I can copy-and-paste, but then I must send the original to the trash, which doubles the time and effort. Is there any way to cut-and-paste?

I have recently switched from a PC to a MacBook Pro.
I have a large number of documents and photographs on a multiterrabite external drive, backed up on a second multiterrabite external drive.
Both external drives are formatted for MacIntosh. This has been verified by agents at an Apple store and also at Best Buy in two different cities.
This is the problem:

Also, the MacBook Pro will not allow me to rename multiple documents or photographs. I can click-and-rename a single one, but this is impossibly time consuming. I can batch-rename in iPhoto, but when I transfer the photographs to the external drive, the rename does not transfer.
I’m reduced to using my wife’s Toshiba to cut-and-past, rename, and transfer documents. It works perfectly. Is there any way to do this on the MacBook Pro?
Thanks!

No, this is a philosophical difference between Apple and Microsoft. Apple believes that it's dangerous to cut a file in case the user never pastes it; in that case the file is lost. Microsoft seems to not have this problem (if I remember Windows correctly) because they don't delete the originating file if it's cut but never pasted.
Even though Macs have a lot of keyboard shortcuts, philosophically Macs have traditionally been mouse-first. This applies to file copy operations. In your case, what a Mac user would do is open the source window, open the destination window (on your second drive), and then Command-drag the selected files from the source to destination window. This is because a normal drag would leave the originals behind, while adding the Command modifier key tells OS X that this is a Move, not a Copy, so don't leave the originals behind.
(In addition there are different rules for drag-copying within the same volume or between different volumes. If you drag between two folders on the same volume, the files are moved. If you drag between different volumes, the files are copied unless you hold down Command to delete the copies on the source volume.)

Two problems in this case. First, batch file renaming is not built into OS X unless you build something with Automator. However, there are many utilities that can do batch file renaming which you can find at macupdate.com or on the App Store. Since I work with media I often batch rename using one of the media managers I have lying around like Media Pro or Adobe Bridge (comes with Photoshop).
iPhoto is a database front end designed to shield the file system from the consumer and let them concentrate on creativity and sharing. As such it is often a poor choice for managing files directly. When you "transferred the photographs" chances are you moved the originals, not the ones iPhoto edited which are stored in a hidden folder.

There will not be a way to do it exactly like Windows. As described above, there are ways to do it "the Mac way." If it is possible to remove judgment on which way is "better" you might find the Mac way to be acceptable, but of course sometimes we simply prefer what we're used to.

Macbook PRo will not boot, MagSafe adaptor light does not work !

Okay... so i have this issue with my MBP where it will not power up.
The light on the magsafe does not show up at all when connected to the MBP. I have tried another magsafe but failed. I have not tried another battery so im not sure if that is wheret the fault lies.
Ive tried the SMC reset holding the power button down for long, but still no result. However, i left the MBP disconnected from the magsafe and went out for the whole day. Came back, connected the magsafe and thought id try again. I held the power button for 10 seconds and the MBP started booting. It wasnt the normal boot im not sure if it was performing some sort of safe boot, but it was doing something, the screen turned transparent white, restarted and i could finally log in. The battery was very low so i left it on charge with magsafe.
One thing i have noticed is that sometimes i wont get the light showing on the magsafe but it may still be charging at that point.
This morning i wake up and its the same issue all over again. It must have stopped charging or something as i left the MBP on with magsafe connected. Now it will not turn on no matter what i do.
If i tilt the magsafe connector at an angle i can see a dim green light but then id have to hold it in that place to see that light.
Please advise on what i should do next. Excuse the long story !

My MacBook Pro will not open any application or program that requires internet, even though I am connected to the web.

My MacBook Pro will not open any app or program that requires Internet, even though I am connected to the web. I recently installed Norton AntiVirus and think it may have changed a setting that I couldn't find. I uninstalled Norton and it didn't help. Every time I open Safari, iTunes or any other program that tries to connect to the Internet, it crashes. Strangely enough, Skype still works, but nothing else.
I have OSx 10.6.8.
I have tried erasing plists, and all the standard troubleshooting, ie resetting modem, restarting computer, reloading Safari from disk.
Any help would be greatly appreciated. Thank you in advance.

Freeing Up Space on The Hard Drive
1. See Lion/Mountain Lion/Mavericks' Storage Display.
2. You can remove data from your Home folder except for the /Home/Library/ folder.
3. Visit The XLab FAQs and read the FAQ on freeing up space on your hard drive.
4. Also see Freeing space on your Mac OS X startup disk.
5. See Where did my Disk Space go?.
6. See The Storage Display.
You must Empty the Trash in order to recover the space they occupied on the hard drive.
You should consider replacing the drive with a larger one. Check out OWC for drives, tutorials, and toolkits.
Try using OmniDiskSweeper 1.8 or GrandPerspective to search your drive for large files and where they are located.
If you are no longer able to boot your computer, then the drive is too full and has become corrupted. You may be able to repair it using Disk Utility on your Installer DVD:
Repair the Hard Drive and Permissions
Boot from your Tiger Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
If this doesn't work, then you will have to erase the drive and install OS X from scratch. From the Tiger installer disc you will choose the Erase and Install install option.

My MacBook Pro will not powerup (even when connected to power supply).

My MacBook Pro will not powerup (even when connected to power supply). The caps lock key is the only light on.

Hi PatB11902,
Thank you for visiting Apple Support Communities.
If your MacBook Pro does not seem to power on, but the caps lock key will light up when you press the caps lock key, you are likely seeing a video issue.
There are several steps that can help troubleshoot this behavior, found at this link:
Apple computers: Troubleshooting issues with video on internal or external displays - Apple Support
Start with these steps:
Reset the system
You can reset the Mac's parameter RAM and SMC.
Start up in Safe Mode.
If your Mac does not start up normally after these steps, here are some additional tips that can help:
Troubleshooting: My computer won't turn on - Apple Support
Verify you have a good connection from your Mac to the wall outlet by confirming the power cord and adapter if present are securely connected and plugged in. To check if the wall outlet is working, plug in a lamp or other electrical device.
If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter.
Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
If your Mac supports user-installable memory, solid state drive, or hard drive, and you recently installed any of these, make sure they are installed correctly and are compatible with your computer. If possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.
If you are still unable to start up your computer after trying each of these steps, visit an Apple Store or Apple Authorized Service Provider (AASP) for further diagnosis. If you plan to visit an Apple Retail Store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only).
Note: Diagnostic fees may apply for issues not covered under warranty or the AppleCare Protection Plan (APP).
Sincerely,
Jeremy
