2011 MBP can't use keyboard or trackpad or external devices following installation of usb prober.
First, I was having trouble with a USB mouse, so I went looking for information about troubleshooting that.
Someone suggested installing USB Prober, which I found and attempted to install.
The installation asked for a restart, so I restarted.
At login screen, I can't use keyboard, mouse (trackpad), or any USB devices.
I'm able to use key combinations at the beginning of boot, so I reset PRAM and NVRAM or whatever they are.
I was able to use key combinations to boot into my Windows partition, and into single-user mode, and into safe mode, and verbose mode.
--Using the Windows partition appears to be useless for fixing the Mac problems, as far as I can see, since I can't modify the filesystem that way.
--In single-user and safe modes, I still can't use the keyboard or mouse.
I found this discussion:
https://discussions.apple.com/thread/4021048?start=0&tstart=0
But that discussion reached no conclusion, and as I said, I tried that one user's suggestion already.
Super frustrated; please be charitable and save my sorry butt.
regards,
herpaferpaderp..afjppr-alurp
No; no no; I don't need the developer forum--I'm not trying to use USB Prober. For all I care, I don't need the USB ports right now. Forget them and the stupid tool, and being unable to use the stupid tool.
I just want to be able to use the keyboard and trackpad, as I was able to before installing the stupid tool.
If you can, help me make everything the way it was before the developer tool. Without going to 781 forums in 36 languages and as many hours. My brain is puny and will implode.

Can´t use keyboard and trackpad at all.
I have a macbook pro early 2008.It was good for sometime but nowadays it is facing some problems in it.When I start it sometimes it works good but sometimes when I use it, suddenly the keyboard an trackpad stop working and I should connect an external mouse and restart it.Sometimes it is OK but sometimes it happens 10 times a day.Can anybody please help m with this situation this computer has a great value to me.
Run an Apple Hardware Test and see if that picks up any useful information, or take it to a repair facility for an evaluation. Unfortunately intermittent problems are sometimes very difficult to diagnose.

Can i use the magick trackpad with the ipad?
can i use the magick trackpad with the ipad? and the iphone?
I'm looking for this same answer, I wonder if any new info. I've gone from posts saying why would anyone want to, and I now see that this is in the ATV section, which actually suits me because the setup I'm using it for is when I don't want to be up in my office on my iMac, but rather in the lounge in front of the big screen with my iPad mirrored to the Apple TV and bt keyboard connected. I wouldn't actually suggest anyone go out and buy a Magic Mouse or trackpad, but since I already have them would like to use it to make things easier when using my iPad as a mini computer with my TV as the screen. I can currently use the iPad to scroll no problem, but if I have to click somewhere specific then I must look at the iPad screen vice just moving a mouse or trackpad and having a pointer show up on my screen. Obviously if my iMac was much closer, I could mirror that screen and my keyboard and mouse would work just fine. (That is if my iMac was newer, but it's not, its a late 2009 model and that apparently is not new enough to be compatible with airplay mirroring.)

Can you install tiger on a power mac g4 with out a DVD drive if so how, I do have have a 2011 iMac can I use that in target disk mode with a FireWire cable any help would be appreciated
Hello,
You need to put the Tiger Install Disc in the 2011 iMac, boot the 2011 uMac into Target mode...
http://support.apple.com/kb/HT1661
Boot the G4 holding the Option or alt key, hopefully the Install Disc in the 2011 iMac will show as a boot choice.
We just want to use the 2011 iMac as a big expensive FW Optical drive, it cannot be installed osing the 2011 iMac itself. -
Flash player on the new mac sarafi can't use keyboard and event listener
flash player on the new mac sarafi can't use keyboard and event listener
cn:英文有些差不好意思，附上中文说明：在flash player web 开发时，我在最新版本的sarafi上，目前出现不能响应键盘事件bug,为了验证是不是我本地问题，我也用在多款别的网页游戏上进行测试，全有这个bug，另外，有时还有那个fp弹出本地 缓存提示设置窗口也点不了“允许或拒绝“那些按钮Now after 5 weeks, you have always not resolved this very important and urgent issue. It seems that Adobe has realy abandonned the actionscript / flash player projects. Why not simply discontinue flash player on desktops too ? Or even better remove or block "automaticaly" all flash players with the final update. That could create a serious issue on the Internet for few weeks but at least that will be honorable end like a Samurai's Seppuku...

Can I use more than one blue-tooth device at the same time on IPhone 4S? Like a wireless headsets and speed and cadence sensor for cycling computer, receive the data and listen music simultaneously
As long as the profiles are different (ex. HID vs AD2P) you will not have any issues. But say if you try to use 2 keyboards at once, it won't work. Or 2 headsets at once. Your scenario seems fine.

DBCA can not use ASM for database storage due to following reason: Could no
Hi
I've a recently installed RAC11gR2(11.2.0.3) on HP-UX
I installed Grid Infrastructure with grid user:

Node2: # id grid
uid=1100(grid) gid=1000(oinstall) groups=1031(dba),1021(asmdba)
I installed the Oracle Server with oracle user:
Node1: # id oracle
uid=1101(oracle) gid=1000(oinstall) groups=1031(dba),1021(asmdba),1033(oper)
Node2: # id oracle
uid=1101(oracle) gid=1000(oinstall) groups=1031(dba),1021(asmdba),1033(oper)

The big issue is... that the DBCA can not see the diskgroups. When I choose ASM Storage it can not see them. It shows the chart in blank and if i try to write the disk group, so the following message appears: can not use ASM for database storage due to following reason: Could not connect to ASM due to following error: ORA-01034 ORACLE not available
What can be passing in this case... ?
Thanks in advanceThanks both
Really the problem initially was because of this:
[INS-06006] Passwordless SSH connectivity not set up between the following node(s): [node1, node2]. CVU may reports "PRVF-4007 : User equivalence check failed for user "user"" for same error
and I had to install node1 first and after node2 manually and perhaps for this the product was not well linked.
I resolved the problem establishing the keys with the wizard and after copying the following files from node1 to node2
/home/grid/.ssh -------> /home/grid/.ssh
authorized_keys
known_hosts
This is the procedure if you run the wizard at the node1.
The problem is that the wizard creates the keys incompletely...

Hello, I have two iphones but one Apple ID. How can I use localization apps for a dedicated device? Tx
On the iPad open Settings/iCloud and delete the account using the button at the bottom. Once deleted log in using the other account. For iTunes Stores use Settings/iTunes & Apps Stores, tapp on the Apple ID at the top then sign out. Once done sign in using the other account. Once you are happy with the changes plug your iPad into your computer to update the backup.

I have a limited storage in iPhone so i bought 20g iCloud. how can i use this iCloud storage in my device to store music and photos?
Welcome to the Apple Community.
You could sign up for iTunes match and use iCloud photo library with optimisation enabled. The later will keep optimised photos on your device and iTunes match will let you access your whole collection and make room for newer content by removing older unplayed items. -

can i use exfat format for my external western digital harddrive so that i can use in both windows and mac?
thanks in advance.
<Email Edited by Host>Yes you can. OS X version 10.6.6 and later can read/write exFAT. Windows XP SP3 and later can read/write exFAT. As posted by Radiation Mac, you can do it from Windows or from OS X.
However, I've noticed Windows to be somewhat picky about drives formatted on a Mac. So, if Windows can't read it, try formatting it on the Windows machine, and see how it works on the Mac.
Posting your email on a public forum isn't a very good idea. It will likely be harvested by spambots and used as the reply-to address for spam it sends out.
Also, most people are not going to send an email to you for similar reasons. Nobody knows who you are, so sending an email to you could be giving a spammer a valid email address.

Can I use my iphone as a tracking Device??
Hi, all out there.!
I just bought the new iphone 3G
This iphone is great and one of the best ever of all the time,
I'm a menufacturing engineer, I used several devices and many computers
in the past and I haven't seen nothing like it.
This is my toy I was waiting for.!!
I've had downloaded several applications already, which they're amazing.
all you can do with your iphone it's amazing.!!
THERE IS ONLY ONE THING, I'M WONDERING IF I CAN DO IT.
It should be able to do it, It has all the tools, I just I haven't seen it.
I'm thinking like a little application that can be used as
TRACKING DEVICE.!!
Can I use my iphone as a TRACKING DEVICE??
Any body knows out there?
How? or where is this application??
DEVELOPERS OUT THERE.!
Can you develop one if there isn't any??
Please, let me know as soon as you can.
Thanks in advance.Hi, Jim.
Thanks for your info.
the second link works now.
I kept trying the first link but I kept getting the same message,
not be able open page becuase invalid address.
Anyways,
Second QUESTION?
Is that software could be use to track a second iphone?
see, I have two iphones and I want to give one to my crazy son,
to track him what **** he's doing.
I know there are seperate devices that I can do that only., but
since I have two iphones already, I don't see a reason why to spend more
money if with the iphones that laready have I can do the same thing.
Please, let me know if that would work or
if there is something else available for that.
Thanks so much again. -
I am trying to get an answer to whether or not I can successfuly use Time Machine with an external HDD connected to an airport extreme. Some forums say yes, some say no. I'm also curious about formatting the hard drive to work both on my wife's MacBook Pro and my PC. Any help would definitely be appreciated.
You may be going on a recollection, that I share, that at one time Apple stated this would be possible:
In fact, Apple’s Time Machine Web page touted this very capability as recently as last Tuesday, as you can see from Google’s October 16 cache of the page
Effortless meets wireless. With a hard disk connected to your AirPort Extreme Base Station, all the Macs in your house can use Time Machine to back up wirelessly. Simply select your AirPort Disk as the backup disk for each computer and the whole family can enjoy the benefits of Time Machine.
But if you look at the current Time Machine page on Apple’s Web site, that text is nowhere to be found.
That was a long time ago, it has never been officially implemented, and at present they specifically say it cannot be done.
In summary, it may work, but probably won't, and even if it does it may not be reliable.
Reference:
Disks that can be used with Time Machine
Time Machine can’t back up to an external disk connected to an AirPort Extreme, or...

Can i use time capsule as a external hard drive
can i use time capsule as a external hard drive
Not plugged in by USB if that is what you were thinking.
You can store files on the TC but you should NOT.
Store files on the TC.
This is asked several times a day.. obviously people are struggling with their latest SSD being too small.
The TC is not suitable for network file server.. but many people having no choice press it into service as such.
Major issues.
1. No backup.. no way Time Machine can backup a network drive. No place to backup to.. So all your files will be at risk. And you will need to buy a third party like CCC to do backup.
2. The TC cannot be partitioned and mixing TM backups and data is not great. It was and is and ever shall be a backup device for Time Machine.
3. The drive is slow to spin up and quick to spin down.. there is no control. In fact the TC is so lacking in controls for even the router side.. that you cannot do more than the most basic of setups.
The following are controls on the hard disk side.
Reformat it. You can name the share. You can do a full archive of the whole disk. This will go at a speed of aprox. 30-50GB/Hr so calculate how long an archive of a full 2TB will take.
4. iPhoto in particular can easily corrupt its entire library with wireless networking causing a disconnection to one photo. Even if you do this;;; do not move your photo library... you have been warned!!
Even apple btw say don’t do it.
http://support.apple.com/kb/TS5168 Although mostly about FAT32 it adds network drives.
5. iTunes can constantly lose connection to the library. The disk is slow to respond.. itunes on the computer will constantly spit out errors. Even in the midst of streaming the TC can spin down the disk due to caching.
6. Do not use any live files on the TC no matter what else you do.. if you edit files in whatever program the file must be on the local hard disk.
7. The only suitable location for most libraries is a computer. You can plug in an external hard disk.
Read pondini for some work arounds.
