Hardware :: Adding A Webcam To Imac Desktop - High Speed Usb 2.0 Vs Full Speed
Dec 20, 2007
I am interested in adding a webcam to my desktop Imac (power pc)- Isight is no longer available- an option that I found is the Ecamm Image- but apparently it is USB and not firewire and it will only run with high speed usb- how do I know which type is on my computer? I checked system profiler but quite frankly wasn't sure of the designations.. does anyone have any experience with this camera, by the way? is USB 2.0 by definition "High Speed"?

Last night my fan kicked into high gear all of a sudden. I shut it down overnight and when booting up this AM I find it still running on high...quire noisy, of course. Is there something overheating? How to make it run at normal speed?

Does it hurt the computer... If the computer is doing something (watching flash, playing a game) that turns on the fan full speed;Does this hurt the computer? There are a few games I like to play and they turn on the fan at full speed (computer gets hot too, on the bottom.)

I bought one of the new-gen iMacs last month--my first Mac! My computer will often start making a low-droning noise, and it sounds like a fan. I have iStat, and usually during this time it will say that my Optical Drive and CPU Fan are both running at around 4000rpm. This happens when there is very little CPU usage too. It's happening right now, and I only have firefox running.

I found this article below when searching on iMac i7 info.We took delivery of the brand spankin' new 27" i7 iMac last week and connected it immediately to our Final Share SAN in about 5 minutes for video editing. Quick tests showed the SAN was connected and working fine.Then today I started really editing on it and I'm dropping frames every 10 to 30 seconds. Now it appears the ethernet controller that is in the new Mac cannot support the speeds necessary to edit video via the SAN. Our 2 year old iMacs can, but the brand spanking new, most powerful iMac cannot.I'm at a loss as to how Apple can improve every aspect of this machine, including the absolutely stunning 27" LED backlit display, but then cut back on something as simple as an Ethernet Controller that should be designed to work with today's equipment running high speed internet instead of stepping backwards to the speed of older model PowerMac machines.

I've got a little problem with my iMac 24" 2.8 GHz Nvidia Geforce 8800GS 500GB. When I start it up, the fans start blowing at full speed. I checked the apple support page for support and found my problem with all the symptoms being correct. The support said I had to reset the SMC by shutting down the iMac, then removing the power cord and all the other one's, wait 15 seconds and then put the power cord and the other one's in respectively. I did this almost 10 times, but my iMac still won't stop making those annoying noises. Maybe it has to do with the SMC fancontrol app my brother installed lately.

My iMac runs perfectly fine; more or less as it did when it was new. In OS X, when I shut down the computer, the fan runs at full speed indefinitely, unless I unplug it or boot back up. When running, the fan is perfectly normal (increases speed a bit when doing something taxing). I've never heard it at full speed before until this started happening. After following the SMC reset procedure with no luck (I'd like to add that the SMC reset only says it relates to fan problems when the computer is ON), I searched a bit and noticed there are one or two cases where a problem like mine was believed to be a motherboard issue, and therefore a costly fix.Â
However, here's the fun part. When booted into Windows 8.1, shutting down the iMac does not cause this issue to occur. It stays silent, as it should, even if I disconnect then reconnect the power. This leads me to believe it's unlikely to be a motherboard issue. However I've wiped, restored, and reinstalled fresh copies of Mountain Lion, Mavericks, and Windows 8.1, and the result is still the same: if I don't want to have to unplug it from the wall, then I have to use Windows to shut it down.Â
So then, my questions are these:
-What is the difference between shutting down from OS X and shutting down from Windows?
-Is an operating system allowed/able to touch BIOS settings?
-Is it possible to still be a hardware problem, given this difference?Â
My default OS is OS X, and it makes no difference if I change that to Windows. I also did a PRAM reset, even though that has nothing to do with fans...

I have a 24" mid-2009 iMac, bought in June. It's behaving oddly over the past week or so. It fails to wake on sleep on the first attempt, but always succeeds on the second. When I say fails though, I mean that it *does* wake up, but goes back to sleep again after a few seconds. The other issue happened today, when I woke it up, in a cold room, the fans started up at full speed (I assume). It sounded terrifying to me as my iMac has never got that loud - not even playing games. I restarted it and it was the same, but died down after a while.

This is one of the biggest problems i have with my macbook. It has only 2 USB ports... on a regular basis i need atleast 4 USB ports and sometimes 5... What should i do about it ?I used one of those china made USB hubs (with colorful leds) but the speed of access to connected devices becomes really slow. I need a really high speed USB hub.

Whenever i open an application both of the fans go to 6000+ rpm in a couple minutes give or take.Strangely web browsing doesn't cause this speed but if a youtube video is played it gets up there fast.Applications such as quicktime and logic gets up there no matter what is played.I have fan control and smcfancontrol, 40GB free, software updated, tried the reset thing (turn off, hold power button, boot), cleared printing operations.The only thing smcfancontrol does for me is it slows down the fans quicker whenever i close all my applications.

Lately my MacBook is making a lot of noise. I was at school working in Google Docs when suddenly a lot of noise came out of my MacBook and I think it's the fans.Â
When I for example watch a YouTube video the noise starts and I'v never had that before. Also when I run my Minecraft server and Minecraft at the same time it starts spinning at 6175 RPM. I know those are resource heavy tasks but I've never had that before.
I installed smcFan to monitor my fans and the degrees (C°) goes from 49° to 91° when I open Minecraft. Early 2011 MacBook 15" on Lion 10.7.3

I have a 2011 mid range mac mini and love the machine, however I have noticed a few things. First off, it seems to be a bit on the slow side when multitasking. I have the standard 4 gigs of ram installed, but running programs like MS Word and Safari at the same time, the machine seems to struggle a bit. Also I have noticed when doing a lot of file transfers via USB, the fan will kick up to high gear for a few minutes and then drop down. Is there something wrong or is this normal? I'm doing a time machine backup of 120Gigs, have safari open and activity monitor open. Activity monitor states 1.16Gigs free, 792MB wired, 961.4MB active, 1.12GB inactive, 2.84GB used. VM size is 150GB, page ins are 962, outs are 380kb, swap used is 10.5MB. Right now the fan seems to have slowed to a mid range mode of some sort and is not in high gear.

I have a MacPro 2.66 quad-core intel. 4gb ram. I have a hard-drive from my old Powermac that i upgraded to 10.5.5 for this computer. Everytime I put my computer to sleep, and then wake it back up. The fans spin up to maximum speed and all the fans are running really loud and then after about a minute all spin to normal speed.

I have a late 2007 macbook pro and recently the fans have been going at extremely high speeds without the MBP being hot at all. I have SMCFanControl and iStat Pro and both of them said my MBP's temperature was around 55C though the fans were going between 4000 and 6000 RPM, I also checked the activity monitor for high CPU usage but nothing high there. I turned my MBP off for 5 minutes with a fan blowing on it just incase it was hot but when I turned it back on the fans immediately jumped back up to 6000 RPM. They're back to normal now but I assume it will happen again. Anyone know what's wrong?

I have had my MacBook for 3 years and it has run great. Recently I have noticed that my exhaust fan has been hovering around 6000 RPM for no apparent reason. When I took that screen shot I only had Safari Open

Returned home this evening to hear my iMac fan making lots of noise, upon checking it was the HDD fan that was operating at 5500rpm. Both other fans were normal. Ambient temperature was 23c and HDD temp was 36c. Normally it's almost silent. It's a late 2009 21.5" base model that has never had an issue in the 23 months that I have owned it. Any idea what the problem is has it gone bad? I restarted but the problem remained I had to shut down and restart to get it back to normal. On another note how do you clean off the dark grey blotchy marks that have appeared at the top of the screen. They don't appear to be on the glass. They started in each corner now they span entire screen top.

My iMac (intel core duo) after a hard drive replacement seems to be running the fans at a high rate of speed. Usually just a few minuets after startup. Before the upgrade they were almost silent and now they are very noticeable. I need to get taken care of or just a result of installing a larget hard drive?Â

Apple has signed on to an industry-wide alliance that will see many companies, including some of the Mac maker's processor and video card suppliers, work together to develop an open format for accelerating specialized computing.Dubbed the Compute Working Group, the organization managed by Khronos Group has been formed this week and includes Intel as well as AMD and NVIDIA, both of whom compete against each other to supply video hardware for Macs in addition to other PC makers. ARM, Motorola, and Samsung are also among the involved manufacturers.The group's focus will be to develop widespread standards for calculating "heterogeneous data" regardless of whether it's onboard a conventional central processor or on a new wave of video cards that can handle some specialized calculations in addition to their normal graphics duties. Like the OpenGL standard, any future standard would be publicly documented and royalty-free.

Crucial lists PC4000 (500mhz) as well as PC3200 (400mhz) for my Power Mac. It has 1gb of PC3200 in it right now. I always thought that you wanted your RAM to be AT LEAST as fast as your FSB. Well...my FSB is 1ghz per processor. SO, would it be a good idea to run PC4000 RAM as opposed to PC3200? From what I gather if I mix them, it will just run the RAM at 400mhz. So would it be substantially faster with say, 1gb of PC4000 as ooposed to 1gb of PC3200 ?

I need advice choosing a wireless router. It will be permanently connected to a pc but I plan on using its wireless for my IBook G4. My wireless card is 54-Mbps AirPort Extreme WiFi 802.11g. I am looking for whatever will give me the highest speed, reliability, and least amount of interference (I live in an apartment complex with multiple networks).

I was wondering. A friend of mine has a Emac 700mhz equipped with a 56k modem. She has an "intermediary" speed internet connection. With that, she can't really view a video - let's say from Youtube. It just keeps hanging. She only has 256mg of RAM which can be boosted to 1G, and I was wondering if by doing so, it would have a significant impact on her Emac capacity to view such content.

I have a Blackbook, it's about 3 years old now and the fan speed has increased to a very high level. There aren't any programs running in the background, this just simply happens when I leave the computer on. I'm assuming it's because there is dust buildup on the internal parts, but it's odd that it progressed from being fine to the stat that it is in today in the matter of days. Is there a way to clean the inside? Apple technician to have a look at it?

I am using Windows right now. I never realized this but my download speed is supposed to be 768 Kbps. Though when I download something my speed is between 70 - 90 Kbps. Is this normal? I ran many virus scans and I am clean.Is there something that is slowing it down? I am also using wireless connection.

Dual 2ghz Power PC G5 with Leopard 10.5.8Recently had it in for a repair, not with Apple (that expired a longggg time ago) because it would only turn on intermittently. They fixed this problem, citing bad components and also replaced the broken optical drive. However when they gave it back to me it was incredibly loud, they stated that they had to reconnect a fan and that was probably what caused the power problem in the first place. I'm pretty sure though that I had disconnected it unwittingly about a week after the power problem started when I opened it up to change the battery... believing that may be the problem at the time.

My Early 2008 MacBookPro 2.40 ghz 4 gb Ram OSX Mavericks machine's keyboard backlight off and fans run at high speed; it seems an exact smc resetting problem.
So i tried the 2 ways of SMC restting procedure; both battery you can move and not, but nothings changed on the situation..
On the way for removable battery; nothing changed but on the way for umremovable battery way; keyboard backlight flashes and gone, but fans are at high speed not changed. So nothing changed.

So I got my first laptop and decided to splurge and got a mac. Now it's great, works great, took me a while to get used to the OS but love my mac now. I use it predominantly for surfing and just basic but am also doing filmmaking. My friend has a macbook pro with 4gb ram and better proccessor, and we used that for film editing, but want to make upgrade mine into one as well (filmmaking laptop). I also may want to use it for gaming (starcraft), photoshop and just a whole bunch of apps and programs. Should I upgrade the ram, get it upgraded for me (get someone to put in the ram) should I even buy ram, is there anything I can do to make a faster processor? Also, my internet is kinda slow, anything I can do to speed it up? Finally, my mac sometimes lags when there's a lot off apps open so I was thinking of upgrading it. I don't have much of a budget (probably not even a 100) so I need something cheap, but don't want shotty second hand stuff. How much can I add, and what else can I do? On another note, Ive been using firefox as my default browser and have added a whole bunch off addons, any other programs I should get for firefox OR any programs I should get for my mac?
