Random packetloss on my new 27" i7

Hello, I just bought a new 27" iMac i7 in late October. From day one I have been experiencing this problem, that is random packetloss resulting I am unable to browse the Internet while it is happening. My iMac is connected to a switch via the ethernet port.
Now, this is not a problem with my home network, I have a Macbook connected to the same switch and it does not happen there. Also to make sure it's not a problem with my home network I did a test. When I noticed my browsing experience started to halt, I opened up Terminal and started to ping my ISP DNS server, and from my iMac there was massive packetloss. I then went into my Windows 7 (Parallels) and pinged the same address at the same time and guess what, no packetloss while Mac OSX was having massive packetloss!
What could the problem be here? Surely it's a Mac OSX problem (driver?)

Gave both a go and got the zoom working and whilst the picture in picture is fun it would be better if apple were able to scale up the Safari favourites folders and mailbox folders. Thank you for your prompt help.

After downloading Firefox 7.0.1, my tabs will randomly move to a new window. Very annoying-how can I fix it? Thanks!

This problem only started after updating Firefox to 7.0.1--
When I'm browsing the internet, the tab I'm on will randomly move to a new window. It's very random and very annoying. Please help me to make it stop!
Thanks!

Are you inadvertently using "tab tearing". If you drag a tab below the tabs bar and then release it it will create a new window moving the tab to it -- not a new feature. There is no animation or symbol attached to cursor -- at least not for me.
I put up with it and generally see it happen as tabs will widen, or my tabs counter will reduce.

Randomly can't name new folders

About once a month or so, the finder randomly stops allowing me to name any new folder I create. The folder name will be selected, but nothing happens when I try to type in a new name, and it just stays 'untitled,' even if I click off of it and reselect it. I can only rename it if I go under Get Info. The only thing that seems to fix this problem is restarting my machine. This time around the problem progressed-- first I couldn't name any folders and now all of a sudden I can't open Get Info w/ the keyboard command. I can only open it by going to the menu. Any ideas what is causing this wackiness??
Thanks

Same here --
I just created a new folder and couldn't change its name. Finder would give me "more info" (permissions certainly not an issue) and allow me to delete (and then recreate) the folder, but not change its name.
Problem came from out of the blue, on a one-week-old system with all OS updates. Also found this old thread, which also suggests a Finder restart: http://discussions.apple.com/thread.jspa?messageID=8989639
So that'll probably do it, but what gives?
Not so impressed with 10.5.7 so far... first a complete system crash while doing no more than downloading updates (a few hours after booting up for the first time), then networking stopped working (see http://discussions.apple.com/thread.jspa?threadID=2003868), now this...

My MacBook Pro randomly freezing ever since new logic board?

My mid 2012 MacBook Pro 13" keeps ok randomly freezing ever since I've had a new logic board fitted after my macbook needed a new one (it was fixed through stormfront which is an official apple retailer). It will just freeze, won't be able to move the mouse or anything, and sometimes when I turn it off by holding down the power button, I can most of the time hear a click, but not everytime. Sometimes it freezes when starting up, sometimes it lasts a while before freezing, but recently it's been more like every 5-10 minutes. Can anyone help me as to why this is happening and what the problem may be? I'm running OS X Mavericks. Thankyou.

Multithread application is crashing random in malloc, free, new or delete

Hi Gurus,
Operating System:
SunOS 5.8 Generic_108528-04 sun4u sparc SUNW,Ultra-80
C++:
WorkShop Compilers 5.0 98/12/15 C++ 5.0
I'm a multithread application using "pthread" and compiled with "-mt -xtarget=ultra -xarch=v9".
My problem is that the server is crashing in differents points (random).
The server can be running without problems, but other times the server crashs immediately.
Always, the server is crashing in the functions "new", "delete", "malloc" or "free".
Normally two functions appears in the top of the stack:
realfree and mallocunlocked with SIGBUS or SIGSEGV.
So, I don't know if I need to install a pacth or is a problem in my server. The problem is that the server can run "n" times correctly and other times crashs with SIGBUS or SIGSEGV in the above functions doing exactly the same.
Could you help me ? Any idea ?
Do you need the stack ?
Thanks and Merry Christmas,
Andres

Randomly freezing cursor on NEW Macbook Pro

I have a new 17" Macbook Pro - 2 weeks old. I noticed almost immediately that there was an issue with either the trackpad being unresponsive OR the computer
is thinking before acting. Anyway, the cursor freezes randomly - sometimes for a second, and sometimes for several seconds. I've been very conscious of how I'm tracking, I have everything turned off in the trackpad preferences.
Is this a software or hardware issue and will I need to bring the unit in for
exchange or repair?
thank you.

Reformat the drive using 'Zero all data' under Security Options and reinstall your system. If it still does it after that, have it looked at.

Mail randomly stops checking for new mail

I've got a PowerMac that keeps Mail open full time. Recently, Mail just randomly stops working and no new messages from my Exchange server are downloaded. This only started within the past two weeks. Either the program is just sitting there with no evidence of function, or there is a continual spinning wheel by my Exchange inbox icon. Restarting Mail seems to be the only solution I've found. I am also running Mail Act-On, Mail Tags, and Mail attachments iconizer. Any ideas on what could be causing this behavior?
Thanks for any input.

Random Safari Problems on New MacBook

Hello Everyone,
I just bought a brand new MacBook. Its awesome but i am having two random problems with Safari that i thought people might be able to shed some light on.
1) My text keeps getting bigger. Every so often i have to go to the view/make text normal size to get it back to normal. its happened randomly about three times in the last few hours.
2) It dosent seem to happen on all message boards but when i go to www.crackberry.com message boards when i click on a topic it brings me directly to the end of the topic or the middle about post #13 or 14....wierd...
Any help would be greatly appreciated...Thanks!

Hi Kevin,
1) My text keeps getting bigger. Every so often i have to go to the view/make text normal size to get it back to normal. its happened randomly about three times in the last few hours.
Maybe you're accidentally performing gestures on the trackpad? Pinching in will make the text smaller, and the reverse (pinching out? ) will make the text larger.
Not sure about the second question I'm afraid. Can you post an example link where this happens to you?

Windows randomly shutting down with new built pc

Morning folks, I'm typing this from my other laptop right now. I just built a tower for gaming and I'm having an issue with windows 8.1. It will randomly turn off anywhere from a minute or less after launching and logging in to 5 minutes after
launching and logging in. I can't seem to tell what's triggering it either. If I try to do anything a screen comes up with a sad face emoticon and tells me that something is wrong but I can never read the full message before the computer shuts
down completely. It's not a soft landing either it's as if I held down the power button. If you can tell me what information to give you I'll try my best. My concern is I won't be able to get error or crash logs because if I try to do anything
the computer shuts down. I'm currently sitting here not moving and letting it sit at desktop to see if anything happens. So far it seems stable to it's only when I'm actively doing stuff.
Concerns I've seen people bring up, yes it is a legal version of 8.1 and yes I did activate the product, I wasn't able to set up my wireless adapter before the computer would shut down so I had to activate it over the phone, it didn't crash during that.
From there I was able to install the wireless drivers successfully and actually access the internet. But as I was heading to a speedtest page the window came up and my computer shut down again. From there it has shut down multiple times after just
minutes of trying to get online and install a game.
I've gone into BIOS and disabled the fast boot that someone has mentioned and I changed my power settings to be on high performance and turned off the timed shutdowns/sleep/driver shut down. I don't think it was any of that though because, 1, it's
still happening and 2, those things were if it was shutting down after so long mine seems more random and in a much shorter time span.
Any help would be greatly appreciated, thank you.
edit: I'm going to keep this updated, I'm at the moment installing my motherboards drivers/utilities. Apparently I forgot to do that from the disk. If that's the case and fixes it then I'll let you all know. I still need to install these
and whatever is on the disk saying 'afterburner' lol. This is my first time ever building a pc and I'm doing it with no help so bare with me. Took me all night to figure out I had a couple things wired wrong with the hard drive and a couple fans.

Okay so after installing the drivers and doing some updates after things were installed the computer ran well for a good few hours. In the mean time I was watching youtube and reading a different forum while I was downloading a game. A couple
hours in the computer BSOD'd again but this time I think it's more manageable as I was actually able to read what it said and it was the more common one saying an issue occurred, and your computer needs to restart and it is collecting data. It then shut
down very quickly as if it were a hard shut down and did not reboot on its own.
I'm going through the same actions again and waiting to see if it reoccurs or if it was a fluke. I don't have the DMP files at the moment because I had to change the setting after reading the guide because it the folder wasn't in windows. It
still isn't there after I made the changes and rebooted but I think that's because an incident hasn't happened yet in order to create the file. In the mean time I turned off fast boot as it seems to be a common instigator of the problem. I'll get
back to you if the problem arises again with the proper logs and dump files as it seems the computer is stable enough to actually navigate there now. Woo! Progress!

What is causing random shut downs on new iMac?

I have a new iMac which is shutting down without any warning! Anyone know if this is a known issue? Is it software or hardware?

Hi FPMS
That sounds like partially seated or a dislodged ram module! I would first check to see if they are both seated correctly, you'll need to push real hard on each module with both thumb's. Use the iMac Installing or replacing memory link below to assist you if someone else installed them for you.

DO NOT use Tech Tool Pro on your Intel Mac. It is only a PPC version. TTP has not released an Intel version yet.
TechTool Pro hasn't been, but the Intel version of TechTool Deluxe was released sometime in the last few days. I couldn't say if that's the version Nancy is using, of course, but it is finally available for download (with instructions to create a bootable CD) for those who have enrolled an AppleCare Protection Plan.

You uploaded the wrong DMP file (the one from windows and not minidmp) but it will do.
This one is Related to ISCTD64.sys Smart Connect software from Intel. I would install the newest software available even if it is the same date because drivers do become corrupt.

Clicking noise, random loud fan, brand new macbook help?

Ok. Here goes:
Just bought a new macbook 2.16, with 2 gigs of ram from an apple store on Friday. I notice that about every twenty seconds I hear clicks that sound like the harddrive is thinking, followed by a slightly louder fan, and then just as suddenly the louder fan goes away. I downloaded IstatPro and my fan would hover around 1799 but constantly go from 1795 up to 1805.
What's strange is that when it gets louder, I don't hear it go up to speed like my Imac used to do, and it's not a higher frequency but sounds like something that was in front of the vent kind of jumped to the side, and now it's just louder.
It's annoying. I would much prefer a constant 1800 whir which is actually quite pleasent.
Let me know if this is normal fan activity. Or any idea of what this could be. Besides that the computer is running great. I'm going in on Saturday and possibly asking for a new computer? Just now afraid that I might not get something better. Also the box the computer came in was really dirty, and a little banged up. Do they used recycled boxes, or could I have possibly got a previously owned unit? Thanks. sorry for the long post...

... we've got the same machine. mine's a month old; it sounds exactly as you describe. the fan noise increases with cpu load, and on mine doesn't start to bug me until around 3,000 rpm and gets real loud ~6. the last laptop I had, a win machine, was absolutely silent until I saved to the hard drive or opened a new program. the keyboard was silent too. so I got spoiled. I did about a 100 page search here and it seems common for the macbook to run noisily and hot. I haven't been able to get a definite yes or no from any genius or tech on whether the fan is designed to ever shut off, but from what I've found out, I would guess not. The cd/dvd drive crunches and clunks when it grabs a disc (there's a recording of this on the apple site indicating it is normal)and when it spins up, sounds like the machine will lift off the desk -- which I have read other users say.
take an hour and search here. between user comments and moderator replies, and the apple tech docs, there's a lot of info.
hope that helps.
