Cleaning with ethyl spirit / rubbing alcohol

Greetings,
Just wanted to get some clarification on whether it is safe to use ethyl spirit/vodka/etc to clean the screen of Ipad 2 or iphone 4g.
I read that it can be harmful for the touch screen, and apple doesn't recommend it, but I just fail to see how. How can any alcohol damage the glass?
I don't care about the oleophobic coating.

Do NOT use any solvents on your iPad, including alcohol or window cleaner. From the manual:
To clean iPad, unplug all cables and turn off iPad (press and hold the Sleep/ Wake button, and then slide the onscreen slider). Then use a soft, slightly damp, lint-free cloth. Avoid getting moisture in openings. Don’t use window cleaners, household cleaners, aerosol sprays, solvents, alcohol, ammonia, or abrasives to clean iPad. iPad has an oleophobic coating on the screen; simply wipe the iPad screen with a soft, lint-free cloth to remove oil left by your hands. The ability of this coating to repel oil will diminish over time with normal usage, and rubbing the screen with an abrasive material will further diminish its effect and may scratch your screen.

Yikes, I cleaned my LCD with 70% Rubbing Alcohol on toilet paper

Hi there,
I had a quick question about my LCD monitor. Before I read all the stuff on the internet about cleaning LCDs, I put 70% rubbing alcohol on some toilet paper and very lightly applied it to my monitor. However, now I am freaking out because apparently this ruins your monitor. Did I permanently mess my LCD up by doing this? Thanks in advance.

Likely you have done no harm. Do you see a mark left behind where you applied the alcohol?

What should I use to clean the trackpad?

I bought iKlear to clean the screen of my MacBook and it works great. I have been using it for years on my iBook. I was reading the directions and it says not to use it on the trackpad. I had used it on my iBook trackpad with no problems. What should I use then to clean my trackpad? Why should I not use it on my trackpad? Anyone have suggestions or used iKlear on their trackpad despite iKlear's warnings?
Thom

A very slightly damped cotton cloth works wonders. Just be sure to wring it out as best you can so no liquid gets anywhere you don't want it to be.

Spilled Rubbing Alcohol on Macbook Pro

Hello.
So I spilled some 96º (~30%) rubbing alcohol on my Mac. I immediately turned it off. Being sure it was dry, I turned it on. It chimes and shows the Apple boot screen, but when it gets into the blue screen, it immediately turns off.
I opened the back lid and unplugged the battery. I plan to let it sit and dry for a few days and then turn it on.
My question is, what could the boot-up behavior mean? Should I be worried?
P.S. I know my guarantee is dead, no worries

Liquid spills, why your MacBook chassis is a one-way valve for spills
After a substantial spill many people will turn their notebook upside down and shake it, not only does this not work, but it spreads liquid havoc throughout your machine and makes things often as bad as possible.
The keyboard itself acts like a one way valve in the case of a substantial liquid spill. While liquid pours into the bottom chassis easy, it does not come out easily at all, and in the case of any spill, most of it will not come out by turning it upside down. Disconnect all power and contact Apple for diagnostics and repair.
Do not attempt to, after a spill, ‘dry out your MacBook’ and test it
After a spill most people invariably try to “dry out” their notebook by various methods, including hair dryers and otherwise. This both does not work, and after a substantial spill of any magnitude, even if the liquid was water, residue is left behind.
There are additionally many very tight places inside your notebook where liquids will linger for a very long time, and cause corrosion or worse.
Immediately unplug your notebook and contact Apple for in shop diagnostics and parts replacement.
In the case of very minor spills people will “dry out” their notebook and feel success that their notebook is working ok, however invariably in nearly all instances after 4-14 days an error / fault pops up and is usually followed by more.
In case of a spill, damage estimates are impossible,.....anything can be fixed, without question.......the question is cost.
contact Apple for in shop diagnostics and cost estimation ....possible parts replacement.

Safe, easy clean-up app for Mac Book Pro?

Any ideas for a safe, easy clean-up app for my laptop? Getting slow... Thanks!

Kappy's Personal Suggestions About Mac Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utility is: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption. Drive Genius provides additional tools not found in Disk Warrior for defragmentation of older drives, disk repair, disk scans, formatting, partitioning, disk copy, and benchmarking.
Four outstanding sources of information on Mac maintenance are:
1. OS X Maintenance - MacAttorney.
2. Mac maintenance Quick Assist
3. Maintaining Mac OS X
4. Mac Maintenance Guide
Periodic Maintenance
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) See Mac OS X- About background maintenance tasks. If you are running Leopard or later these tasks are run automatically, so there is no need to use any third-party software to force running these tasks.
If you are using a pre-Leopard version of OS X, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced after Tiger. (These utilities have limited or no functionality with Snow Leopard, Lion, or Mountain Lion and should not be installed.)
Defragmentation
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive except when trying to install Boot Camp on a fragmented drive. But you don't need to buy third-party software. All you need is a spare external hard drive and Carbon Copy Cloner.
Cheap and Easy Defragmentation
You will have to backup your OS X partition to an external drive, boot from the external drive, use Disk Utility to repartition and reformat your hard drive back to a single volume, then restore your backup to the internal hard drive. You will use Carbon Copy Cloner to create the backup and to restore it.
1. Get an empty external hard drive and clone your internal drive to the
       external one.
2. Boot from the external hard drive.
3. Erase the internal hard drive.
4. Restore the external clone to the internal hard drive.
Clone the internal drive to the external drive
1. Open Carbon Copy Cloner.
2. Select the Source volume from the left side dropdown menu.
3. Select the Destination volume from the left side dropdown menu.
4. Be sure the Block Copy button is not depressed or is ghosted.
5. Click on the Clone button.
Destination means the external backup drive. Source means the internal startup drive.
Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears. Select the icon for the external drive and click on the upward pointing arrow button.
After startup do the following:
Erase internal hard drive
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your internal hard drive (this is the entry with the
       mfgr.'s ID and size) from the left side list. Note the SMART status of the
       drive in DU's status area. If it does not say "Verified" then the drive is
       failing or has failed and will need replacing. SMART info will not be
       reported on external drives. Otherwise, click on the Partition tab in the
       DU main window.
3. Under the Volume Scheme heading set the number of partitions from the
       drop down menu to one. Set the format type to Mac OS Extended
       (Journaled.) Click on the Options button, set the partition scheme to
       GUID then click on the OK button. Click on the Partition button and wait
       until the process has completed.
Restore the clone to the internal hard drive
1. Open Carbon Copy Cloner.
2. Select the Source volume from the left side dropdown menu.
3. Select the Destination volume from the left side dropdown menu.
4. Be sure the Block Copy button is not selected or is ghosted.
5. Click on the Clone button.
Destination means the internal hard drive. Source means the external startup drive.
Note that the Source and Destination drives are swapped for this last procedure.
Malware Protection
As for malware protection there are few if any such animals affecting OS X. Starting with Lion, Apple has included built-in malware protection that is automatically updated as necessary. To assure proper protection, update your system software when Apple releases new OS X updates for your computer.
Helpful Links Regarding Malware Protection:
1. Mac Malware Guide.
2. Detecting and avoiding malware and spyware
3. Macintosh Virus Guide
For general anti-virus protection I recommend only using ClamXav, but it is not necessary if you are keeping your computer's operating system software up to date. You should avoid any other third-party software advertised as providing anti-malware/virus protection. They are not required and could cause the performance of your computer to drop.
Cache Clearing
I recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, Mountain Lion Cache Cleaner 7.0.9, Maintenance 1.6.8, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc. Corrupted cache files can cause slowness, kernel panics, and other issues. Although this is not a frequent nor a recurring problem, when it does happen there are tools such as those above to fix the problem.
If you are using Snow Leopard or earlier, then for emergency cleaning install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. (AppleJack works with Snow Leopard or earlier.)
Installing System Updates or Upgrades
Repair the hard drive and permissions beforehand.
Update your backups in case an update goes bad.
Backup and Restore
Having a backup and restore strategy is one of the most important things you can do to maintain your computer. Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. You can never have too many backups. Don't rely on just one. Make several using different backup utilities. My personal recommendations are (order is not significant):
     1. Carbon Copy Cloner
     2. Get Backup
     3. Deja Vu
     4. SuperDuper!
     5. Synk Pro
     6. Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance and backup and restore.
Always have a current backup before performing any system updates or upgrades.
Final Suggestions
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity or 20 GBs, whichever is greater, as free space. Avoid installing utilities that rely on Haxies, SIMBL, or that alter the OS appearance, add features you will rarely if ever need, etc. The more extras you install the greater the probability of having problems. If you install software be sure you know how to uninstall it. Avoid installing multiple new software at the same time. Install one at a time and use it for a while to be sure it's compatible.

Most if not all maintenance is for troubleshooting problems. If your computer is running OK, then there isn't really a thing you need to do except repair the hard drive and permissions before installing any new system updates.

If you have a external USB enclosure - trying installing your hard drive in that enclosure and connect it to your usb port - restart your macbook while holding down the options key. If you Macbook boots to your desktop then you have a faulty cable. If you get the same error, then your hard drive just died on you.
good luck.

I cleaned my Macbook pro too much and I think it's damaged.

How do I get rid of streak marks that are really bothering me?

Pledge will leave residue if you use it often.
You need to find a cleaning agent that can remove the Pledge.
Diluted Windex should work.
But BE CAREFUL as Windex and other glass cleaners contain ammonia and can damage your computer if not used properly.

Can't zoom with trackpad in safari how can i solve that?

Help please!!!
can't zoom with trackpad in safari how can i solve that?

There are two places on settings where you can tunr zoom on or off for the trackpad.
They both need to be on for it to work.
The first is under: system preferences>trackpad>scroll & zoom, then you just need to chekc the box to turn zoom on. ( this is the one you already have checked i think)
The second is under: system preferences>universal access>seeing, then check the box that says zoom.
Hope this helps.

I am having problems with my Magic Trackpad. All I can do is move the cursor and single click. I using the most current version of Lion.

In System Preferences > Trackpad > your preferences should look like this screenshot. If they don't then some 3rd party driver is conflicting. The most common conflict is USBoverdrive.

HT1553 I want to do a clean install of Mountain Lion. Can I do this without a DVD version of the OS, and can I restore only specific things like iPhoto and iTunes libraries from Time Machine backup.

I want to do a clean install of Mountain Lion. Can I do this without a DVD version of the OS, and can I restore only specific things like iPhoto and iTunes libraries from Time Machine backup.

Mountain Lion is only available as a download, so there is no DVD to purchase. What you can do is download ML and then stop it from installing as soon as it's on your drive. From there you can make your own bootable ML flash drive.
When your purchase and download Mountain Lion, it will end up in the Applications folder and automatically want to install. Press Command+Q to stop the install and exit. The installer will remain on the hard drive.
1) Right click on the installer and choose "Show Package Contents".
2) A folder will open on the desktop. Drill down to Contents > SharedSupport and double click the disk image InstallESD.dmg to mount it on the desktop.
3) From here you can either burn a DVD, or copy the contents to a flash drive. Personally, I would strongly suggest using an 8 GB flash drive formatted as Mac OS Extended. You will be able to boot to it in about 30 seconds instead of at least 10 minutes off of a DVD, and it will install MUCH faster. Make sure the flash drive is empty, or you've copied anything off it it you need as it will need to be erased.
4) Don't just drag and drop the contents you see in the open disk image to the flash drive. It won't boot that way as it will be missing some hidden files. Open Disk Utility. You will something similar to this:
5) To accomplish the above, highlight either the flash drive's single partition (as I did), or the item at the bottom (Mac OS X Install ESD), which is what you will see with the Lion disk image mounted. It doesn't matter which one you pick. You'll then have the option to select the Restore tab towards the upper right. Drag and drop from the left column into the Source and Destination fields as shown above. If you've already erased the flash drive, you can uncheck the box. Click the Restore button.
You've just made your own bootable Mountain Lion USB Flash drive installer. Once you boot to the flash drive, run Disk Utility first to erase the drive you want Mountain Lion on, then continue with the install.
As far as restoring your iPhone and iTunes libraries, I couldn't tell you. So I wouldn't do any of the above until someone else chimes in with a way to do that after a clean install of ML.

How to clean finger prints off the screen??

Some people say buy solutions from a computer store like iKear $30 and others say just get a vinegar solution and dilute with water 50% and that would do the trick. Any thoughts as to what is best to use?
Max

The user guide that was in the box when you purchased your MBP says to simply use water. I clean my screen off with a damp washcloth (just dampen one corner) & then dry it with the other side of the washcloth. Make sure you do not press very hard on the screen!! This method works great on the rest of your laptop too. It leaves the surface feeling like new, especially the keys. Two other things to note: 1) I used the word "damp" not "soaking wet." Ring out the corner of the towel as much as you can.
2) remove the battery & disconnect the power adapter
I don't have the guide with me for the exact words, but I clearly remember that it said not to use chemical solutions. Vinegar is acidic (even when 50/50 with water)...common sense would tell you not to put that on an expensive LCD display!! So just use water & a soft towel. It's what Apple recommends & it's much cheaper (free, in fact) than third-party chemical cocktails.
Merry Christmas to all!
