Macbook Pro Crawling, noticing connections repeated from certain IPs
My Mac book Pro has been crawling lately, I have reinstalled and wiped the hard drive, and I am suffering the same problem, particularly on wireless networks, with an SSID. I feel I may have acquired the issue when our network was not initially secured.
Here is a sample of what is quite common in my log:

Thanks for your help!
Since I've been trying to connect to my Mac from my windows work machine, I was surprised at how easy it was to access at least my home folder at ftp://[email protected] with just a simple username and password login. If someone thinks they have these items, they may be trying to connect, or perhaps it was a machine that used to be at your IP address.
Disabling all file-sharing under System Preferences>Sharing along with maintaining your stealth mode (not broadcasting that there is a machine at your IP address) ought to stop any possible attempts. If the continual logging is giving you a problem, try and turn off the logging attempts. That may be a source of your performance crawl as well.

Both my iMac and macbook pro will not connect to a certain web site?
Both my macs (21" new iMac & a 2008 macbook pro) will not connect to foxcycling.co.uk. I know the site is live as I can access on my iphone and ipad.
From what I've read on the forums its a settings issue which probably migrated from the macbook to the iMac when I migrated the data.
Very frustrating ....
Any idea's and simple solutions?
Both systems up to date etcOK, OS X does not include Adobe Flash. The website is probably Flash based. Chrome has Flash incorporated into it. If you want to download and install Flash visit Adobe's website and download Flash for your system.

How do I print from wifi-connected MacBook Pro to printer connected via USB to Win7 PC?
This is really frustrating, and I did not think that anything could be this difficult on a Mac. I have a Windows 7 Home Premium desktop PC connected via ethernet cable to wireless router, and a printer connected to the PC via USB. I recently bought my first ever Mac - a MacBook Pro, which is connected via wifi through the same router. All I want to do is to print files from the MacBook Pro on the printer connected to the PC. I have spent a LOT of time searching all over the web. Have tried some 2 or 3 different methods but none of them work for me, e.g. I shared the printer on the Win7 desktop and then added the printer on the MBP with the IP option with LPD/LPR Protocol, after enabling LPD Print Service on the PC. The printer gets added but when I give the command to print from the Mac, the print job shows up on the printer queue but the "Printing" soon changes to "Error Printing" (or something like that) and nothing gets printed. Then, I have to switch off the printer, remove the print job from the queue and switch on the printer again to get it out of the error state.
I also tried setting up the printer on the MBP using CUPS Admin interface, i.e. localhost:631. Again, printer gets added but document does not print. The third way I tried to add the printer was using the Windows option in the Add Printer dialog, and typing in an smb: URL but no luck with that, either.
Please, can anyone help me? This is driving me crazy
Oh, and the devices are:
1) Windows 7 Home Premium Desktop PC
2) MacBook Pro running OS X Mountain Lion
3) HP Deskjet F2110 printer
Thanks...
- AjoyFirst Install Bonjour for Windows on your Windows machine. This will allow the printer to be discovered.

How do I FTP files from a security camera to iCloud so they can be retrieved back to my MacBook Pro whenever I connect when travelling?
RussDo you want to watch the live feed of your secutiry cameras or recorded footage?
In either case, I don't think iCloud is your solution.
For the first one, check with your security camera software, they usually have this option of broadcasting, so you'll know how to access it.
For the later, you should use something like Dropbox (www.dropbox.com), since iCloud file sharing is, up to this date, app restricted.
Hope it helps.

Hello chrispyw,
If your content is still being displayed incorrectly, I would check the resolution setting for the built in display with this article:
OS X Yosemite: Adjust your display’s resolution
If it keeps happening whenever you use AirPlay then I would use this section of the following article to reset the display system:
Apple computers: Troubleshooting issues with video on internal or external displays
Reset the system
You can reset the Mac's parameter RAM and SMC.Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
Thank you for using Apple Support Communities.
Regards,

My macbook pro no longer connects to my TV with the mini dvi to hdmi adapter. A while ago the computer fell down and hit the cable. How can I tell if the computer is working ok. Doesn't show mirroring any more. Was working while watching a movie but when I pulled it out from the computer and put it back in the system would no longer mirrorr the screen on the TV.
The best option is an appointment at an Apple store genius bar. The evaluation will be for FREE!

How can I download my TV episodes to my Macbook Pro. I bought them from my iPad2, and I looked for them with the same AppleID on iTunes Store and they wont download to my iTunes.
What country are you in ? Depending upon what country that you are in then you might be able to redownload them on your Mac's iTunes via the Purchased link under Quicklinks on the iTunes store homepage
If you're not in a country where TV programmes can be redownloaded then connect the iPad to your Mac's iTunes and use the File > Devices > Transfer Purchases to copy them over from your iPad -
I got my Macbook Pro 17inch (early 2011) back from Apple (they had to replace the logic board) 3 days ago, I had a terrible experience as the genious who gave me my solid state disk for safekeeping lost my disk's brackets thus I had to wait 2 more hours until they find one after 10 days of waiting for the repair. I noticed some weird sounds, like somehting is moving with the mac 1-2 times, even if I have no mechanical parts other than the fans, but my real issue at the moment is that my microphone is not working. I can see the mic in the System Info however and in Audio Midi Setup. In the Audio Midi Setup I see that the master chanel is turned off and I can't turn in on. Ch 1 and 2 are on full. I also noticed the first seconds after the comp. boots the blue bar goes to the middle in the System Preferences -> Sound -> Input. Any ideas what to do or try? I do not want to go back to the apple store as it is 50 minutes away from here and I need my laptop as a computer science student. Everything else is working perfectly.
You need to call both the store that did the repair and Apple directly, warranty service or Apple care, and report this problem with both of them and get a ticket number of some kind (some kind of verification number) that the unit just came back from major service with this problem and that you want it fixed when you can lose the use of it, which is not right now.
Without doing something like that they could easily say it is damage not covered under the normal warranty.
God knows what the repair center did and did not do to it while it was there.
And depending on when you actually bought it the warranty could run out in the mean time. -
MacBook Pro can't connect to wireless internet
I have a MacBook Pro that I have had from about 3 years now. It's been great but earlier this week, it wasn't able to connect to the internet here at my school (college). I didn't think too much of it because my schools internet is always spotty and goes down from time to time. Yet when I go on to my computer tonight nothing I do with my airport or computer will get my webpages to say anything other than "Server not found". I tried turning off my airport then back on and reselecting my network because usually that helps. It would say it connected and I would have full bars but still the same error message. I tried again, and when I did it this time, I did it from within the system/network preferences. When I did this, I watched the connection of my airport go red, then I would connect and it would go to yellow saying I had no IP address. I would then sit and wait and eventually it would fully connect giving me the green go-a-head. But, again when I would open up my internet, I would get the "Sever not found" message. I would then quit my firefox all together and tried again that way and still same massage. I restarted my computer and tried again...nothing. I became more concerned because my roommate could get on the internet just fine and I could use the wireless in my room through my phone. I was consered that now this was a matter with my computer and not just the internet, so to make sure I got out my ethernet cable and hooked it up with my connection in my room. This would work!
So my question is...
My roommate brought up the possiblity that this problem is with some sort of chip in my computer that helps me connect wirelessly to the internet and that it has gone bad and needs to be replaced. It this so? or is there something else I need to be doing? (and I have been trying lots of thing) This is vital to me getting my work done because we are in the middle of the semester and I need my wireless!!
Please help!
Thanks!thats... odd
thats a real world IP address. So that means you dont have an actual router doing NAT.
It's also very unsecure. I HIGHLY advise tweaking your home network very soon. Without alot more info theres not much that I can really advise though.
You said your roommate can get on the wireless fine - what IP address does he/she get?
Also, i think you said if you plug in with a physical wire it works as well - what IP address there?
Do you know if you have an actual router? Or is this simply a cable or dsl modem? -

Can i install windows 7 via bootcamp (on my MB Air) while using remote disc? I put the windows 7 disk in my macbook pro drive, and connect to my brand new macbook air via remote disk. In bootcamp (on my air) i allocate the partition, then i click install, and bootcamp will not see the disk from my macbook pro's drive. How do i get the bootcamp assistant running on my MB air to automatically find the disk in my macbook pro with the ISO image of windows 7? The remote disk on my air can find the cd but bootcamp will not begin installing it. Anyway to do this without buying the damned usb drive?
I don't know first hand if you can use the Remote Disk option with Windows but as of 10.7.2 you can now use BCAssistant to make a bootable USB (thumb drive or external disk) W7 installer with the Boot Camp drivers installed also. Have you tried that yet?

when i tried to reinstall my lion to macbook pro 15'' and connect it to the net it says no installing information for this machine? what's that means??
The internal drive has failed.
Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional — ask if you need guidance.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Keeping your confidential data secure during hardware repair
*An SSD doesn't need to be zeroed.
