I have had my iMac in storage for the past 3 years. Now I want to get on my computer but can't but am unable to. I'm very frustrated as to what to do. Please help.
I have had my iMac in storage for the past three years. Now that I finally have it unpacked I want to get on it but am unable to due to the fact I can not remember my username and password for this computer. It runs OS 10.4 Tiger. Nowhere have I been able to find where i wrote this info down. Need help.
Get the Mac to set up an additional administrative account. You can then change the password on your old account.
Start with your computer power off. Hold down command-s. Power on your computer.
Type in the following:
The first two commands will depend on your release of Mac OS X. Look at what is typed out in the console to determine the exact format.
# Type the follow two instructions to access the startup disk in read/write. Press return after each command.
# in case of partial success repeat this command until errors go away.
/sbin/fsck -fy
/sbin/mount -uw /
cd /var/db
pwd
#List all files. The l is a lower case L.
ls -a
#The move command acts as a rename command in this format.
mv -i .applesetupdone .applesetupdone.old
# reboot your mac
shutdown -r now
Once you've done that the computer reboots and it's like the first time you used the machine. Your old accounts are all safe. From there you just change all other account passwords in the account preferences!!

The above the idea came from a post by JoseAranda at September 9, 2006 3:48 AM

You will need to scroll down to see this post. Search for applesetupdone
This method is mentioned in an apple support page without giving an explanation.
Once you have a new administrative account, you can change the password of your old administrative account

Help!! I'm using a Mid 2012 MBP retina 2.3Ghz i7 with 8GB of ram 256SSD. for the past 2 years my write speeds has been consistently on 400MB/s and up via black magic test. but now it only have 100MB/s going down to 80MB/s. what should I do???? I have already cleaned and even restored my MBP still it's on 100MB/s. please help. I have to finish tasks on a timely manner.
No. This requires completely repartitioning the SSD. You can do that only by using the Network Recovery method or the method I outlined. My method preserves all your data and doesn't require doing a slow Network Recovery. But if you wish to do that instead. The purpose of the whole exercise is to "clean" the SSD of garbage collected during use that tends to cause the SSD to slow down as you've described.
Install OS X Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Security button. Set Zero Data - one-pass, click on the OK button. Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer. -

Hi, I've used four different Groups when emailing for the past few years, and suddenly they have stopped working. I've tried creating new Groups but that doesn't work either. I haven't changed or done anything different and it is driving me mad......can anyone help, please?!
Thanks for that information!
I'm sure I will be calling AppleCare, but the problem is, they charge for the phone calls don't they? Because I don't have money to be spending to be on the phone with a support service.
In other things, it seemed like the only time my MacBook was working was when I had Snow Leopard without the 10.6.8 update download that was supposed to be done to prepare for OS X Lion.
When I look at the information of my HD it says that I have 10.6.8 but that was the install that it claimed to have failed and caused me to restart resulting in all of the repeated problems.
Also, because my computer is currently down, and I've lost all files how would that effect the use of my iPhone? Because if it doesn't get fixed by the time OS 5 is released, how would I be able to upgrade?! -
ical (the calendar program) that came with this apple mac pc suddenly stopped working. When I pulled the icon from the desktop, it then disappeared from the computer.I have been using it from the desktop for the past two years, without trouble. It has uninstalled itself, without my intervention and has eradicated all traces of it, including all my entries from the computer memory. There is no program in the applications list. Can you say why this may have happened please?
I opened one of the .calendar folders. There was a folder named Events which had either one or some files ending .ics. I opened several of these, which put up a dialogue window showing some parameters with data strings attached as follows :-

I have been using a Lightroom 5 including recent upgrades on my Mac Pro laptop for the past 1 year. This was purchased as an upgrade from Lightroom 4 for which I have a serial number. Today I purchased a new Macbook pro and loaded my Lightroom 5 however it is asking for my serial number which I have misplaced. I am unable to trace my serial number anywhere. I have even checked my adobe membership to locate my serial number but it does not seem to have any record which is strange as I have been using this software for over a year now and the previous versions since 2009. Could someone help me in my predicament.

I have an iphone 2g unlocked for tmobile. For the past 2 years it has worked fine then out of no where I get this message "your selected cellular network is no longer available" and the service cuts in and out all day. It can't find tmobile on my phone for some reason but for 2 years previous it could no problem? tmobile says it is a problem with my phone and not their service.
Any ideas what to do?I would just explain that this just started happening, that nothing has changed on the phone, that it is an original iPhone and I wondered if they are implementing a change in coverage with their Edge network in my area.
If you restore your phone, you will be given an option to back up your phone at the beginning of the process (see step 6 here: http://support.apple.com/kb/HT1414). You will be given the option to restore to that backup at the end of the restore process. Your messages are stored in the backup so restoring to the backup will return the messages to your phone. Be sure to import your photos and videos to your computer (see http://support.apple.com/kb/HT4083) and back up your contacts somewhere before restoring your phone as these sometimesget lost in the restore process. -
I'm having trouble buying a season pass for The Americans. I have purchased passes to Justified for the past 4 years with no problem. Can't figure out why this purchase won't work.
What is the problem that you are having ? If you are getting an error message then what does it say ?

So, for the past two years I've shared an account with my sisters. This year I got my own laptop and I want to take my device off that iTunes, but still keep the music I bought. How do I do this?
You should be regularly importing your photos on your device to your computer. That is where all of your photos should be permanently stored. What is on your device is selected when you do a sync to iTunes. Once you select your device, you click on the Photos tab, and select which photos, albums or events you want specifically downloaded to your phone. If they have all been backed up to your computer, then you will be able to select whichever ones you want on your new device.
Contacts would be backed up as a part of the backup process to iTunes. Here is a support article with specific information about what is backed up:

Hi there,
I have a 13-in Macbook Pro, 2.4 GHz Intel Core i5, Mac OS X Lion 10.7.5.
My wifi only works at my house. it has been fine for the past 2 years everywhere else, but now the wifi says its connected, but the internet doesnt work.
I have already tried a number of things to resolve this as it has been happening the past 2 months by looking on here and some have worked, but I can't seem to get anything to work anymore.
When I run the Network Diagnostics the Network Status is the following:
wifi- Green
Wifi-settings- Green
Network Settings- Red
ISP-Red
Internet Server-Red
I am home right now so the internet is working fine, but seeing as I use my macbook for school and work, I need it to work everywhere.
Thanks!jcupat,
when you ran the Network Diagnostics above, was that run from home, or was it run away from home?
If it was away from home, do you get all green lights when you run it at home, or does it work properly despite not all of the lights being green?
Does your school or work allow anyone’s computer to connect wirelessly, or do these sites require whitelisting of some sort to permit a computer to use their respective networks? -
There has been no signal in Springdale, UT for hours today. there is no way to contact Verizon (Calling or Web Chat). Service has been deteriorating for the past two years in the area. Worse fact is no one at the company seems to care. Right now the immediate issue is no service. I cannot do business this way.
You used the data. Verizon can not see what it was sued for. However your phone can see whats apps used the data. go to settings-data usage- there will be a place that says data usage cycle. line the dates up with your cycle. then there will be a bar graph below that extend bother white bars one all the way to the left and one all the way to the right. after those are extended below that will be a list of apps, there should be one that used over 2 gb and that will show you what app used that data in her purse
