I bought a Belkin powered USB hub and hooked my MacBook Air Superdrive to it and it won't work. I was under the impression it would in a powered USB HUB. Anyone share any experiences with me on this?
I had a powered USB hub attached to my computer, w/ a mouse and two printers attached to it. For a while, it seemed to work fine, but then the printers wouldn't work, and I had to connect them directly to the computer. I decided the problem must be with the hub, so I went out to MicroCenter and bought a new powered hub. Again, it seemed to work for a while, but then the printers again wouldn't work. There aren't enough USB ports to run all my peripherals so I have had to disconnect a backup USB hard disk. The hub is now disconnected entirely, and I have to switch connections around. Needless to say, this is a pain.
MacBook Pro 17" 2.33 GHz Intel Core 2 Duo, 4GB Ram, w/ external 22" ViewSonic monitor, running OS 10.5.8
I have a 15" PowerBook G4 1.33 Ghz and I discovered that the provided USB ports do not power such devices as portable hard drives or audio interfaces.
So I heard that you need a POWERED USB hub.
I get one, Plug it in. And the PowerBook still doesn't recognize my external hard drive.
My hard drive has two wires on the opposite side from the enclosure that connect to female USB ports. I run an extension cord from one of the males to the other USB port on the PowerBook which is said to work but that also does nothing.
I just replaced my hard drive in my 2007 MacBook Pro. However, when I now put a disc in the superdrive, it only reads it occasionally. Most of the time, it just spits the disc out.
I've tried my tiger install disc, leopard install disc, and snow leopard install disc.
NOTE: I cloned my old hard drive to a back up and put it back on the new hard drive once installed. So, I'm up and running, but I want to reinstall leopard as a fresh install, but the superdrive doesn't want to work.
I picked up a 13" '08 Macbook pro, everything's great apart from a dvd being stuck in the drive.
I've tried all the usual tricks that come up on google, holding eject/trackpad on start up, eject in commands/itunes and the thin piece of card under/over the disc but nothing has worked.
When holding eject it sounds like the disc hits something as it tries to eject but due to the felt I can't see inside to see what it is?
I was thinking that if i bought an external MOBILE hard drive (un-powered) i could take it with me sometimes when i need it in UNI (in Lectures where there is no power source to plug drive in), but also attach it to the mac and since it is un-powered and mobile time machine will work without needing external power.
I bought a 1.5GHz G4 Mini with Combo Drive. Ordered a Superdrive via eBay and fitted it (2 minute job - done it many times previously). Panasonic Model UJ-846-B march 2008. On this occasion, the drive fails to work. I can insert a disc and eject it (using the button on the front of the drive) but the drive isn't "seen" by the Mini. [URL] I received a second drive from the seller and it has the same problem. I assume that it doesn't have the correct "driver" firmware installed.
I was thinking, for the next generation MacBook Air, would you want a slightly thicker (thickest part is 0.9in, tinnest is ~0.35in) laptop with a built in Superdrive, more ports, etc, or would you perfer that Apple moves away from this with a thinner computer (0.1in thinnest, 0.6in thickest), but with same limited ports.
I would actually perfer thicker with a superdrive, since I want an air but I want it to be like a MacBook but thinner. What do you think? Btw, this is assuming the regular MacBook does not change in size, since that would sway peoples opinions.
I recently got a Macbook and have a iPhone and iPod shuffle. The thing is there isn't enough usb ports on the Macbook so I had to get a hub. The hub I got IS self powered and does not require a external power adapter. My concern is that I am withdrawing too much power from my usb port through this hub. It is a 4 port hub and a External HDD ( has own power supply), Optical mouse is connected to it. also I charge my iPhone and shuffle via the same hub.
I am afraid that there is power limit feature and it will fry my computer. I notice if I boot in boot camp to windows. Windows will display a error message telling me, I am not allowed to have this many device drawing this much power. Anyone know if I should be okay as long as OS X doesn't give me a message or should I really consider getting a USB hub with its own power adaptor?
I share a quite common problem. My macbook doesnt boot-up.It does power on and gets into the booting up process but nothing happens... To be more precise, after powering on the MB, the grey display appears and after a while the apple logo and the circle of lines starts to move around.
After that nothing else happens...
I ve tried everything possible... SMC reset, PRAM reset, verifying the disc by booting up either from single user and check it with fsck or with the booting disc and run all the verifying tests and the repair ones... Everything there were just as NORMAL...The OS refuses to open either in normal mode, or at safe mode or even the verbose mode, though it does boot up in single-user mode.
I even took out the HDD and place it in a HDD cover and then plug it as an external device to my other MBP. I run the tests once again but everything seems to be NORMAL again...The only thing that is left to check is whether the boot files have any problem...
My battery seems to have lost the plot. I can turn my machine on when running off the battery and it fires up as normal. Once it gets to my desktop everything is frozen. The arrow is always stuck in the top left corner and the only thing that works is the power button, but I can't even turn it off because I can't select switch off.
It works fine if I take the battery out and run off the adaptor but kinda defeats the purpose of having a laptop.
A friend and I will be going to Europe in a few weeks. We both have iPhones and I was hoping to charge both of them using my Air so that I do not have to bother with buying extra power converters. I already have the UK and EU plugs for the Air adapter.
I've been trying to find a good, solid powered-USB hub to use with my Macbook Pro. I tried the Belkin 7-port, which had good reviews, but it just stopped working after 2 weeks, and it was never powering self-powered USB hard drives properly (even though it was supposed to).
So I'd like some recommendations for a good USB hub that has sufficient power to use with self-powered USB hard drives and that won't slow down or stop working when i connect too many devices.
Like many others, I'm thinking of replacing my HDD with an SSD and replacing my optical drive with the original HDD. I plan on using the SSD as my boot volume and the HDD for storage. Part of the reason I am switching to an SSD is that I carry my laptop around quite a lot and don't feel confident that the HDD won't fail because of all the motion.
My question is: Can I leave the HDD powered off until I want to use it? Thus saving battery life and reducing the risk of HDD failure from being moved around too much. I would like to be able to mount the drive when I want to access the storage and unmount it when it is not in use. Is this possible?
Info: MacBook Pro (13-inch Early 2011), Mac OS X (10.7.3)
My MacBook has suddenly gone dark. It charges fine and the battery lights show there's charge. The screen is very dark when powered up? When I turn the brightness down fully, then go to turn it up the screen lights up for a second then goes again?
i need a good usb hub that can be powered off the other usb port on my 13in macbook pro cause i have a portable usb hd that when one usb port wont power it can get power off the other and operate but that claims the other port
