Excessive lag in VI on Mac, but not Windows

I have created a VI that accepts user input to collect, save, and open voltage waveforms from a DAQmx board. It is a while loop and a state machine with a lot of information in it so I understand that efficiency might be an issue. This lag only exists, however, on a Mac, whether it is compiled into an application or run through LabVIEW. The VI on my Windows 8 machine has no issue handling 1000 samples, but when I run it on my MacBook, asking for 10 samples creates approximately a 20 second lag between data aquisition and data display, and a 30 second lag when asking for 100 samples, etc. This is the case for my Mac desktop as well. Could this be an issue with the way a Mac handles this information/memory, and are there any quick fixes to reduce this lag? Thank you for your input!

It would be helpful if we could see a bit o' code.

Scrolling over images in Word is choppy & lags on Mac, but not Windows

I have a large Word document with about 10-15 images that is about 50 pages long. When I scroll through the document, it lags in an extremely annoying way past the images and graphs; it is very choppy and almost freezes the program. I'd be willing to send admins a video of my screen showing what is happening.
I have 8 GB of RAM, I have a mid-2014 model MacBook Pro, and have no other windows open, and my machine is able to use multiple Adobe programs without flinching. It's not my computer but it IS how my computer/word is handling the document.
I opened this exact same document on a windows computer and it works perfectly well. I am able to scroll as I would on any website, and the content of the document does not affect my scrolling speed or display. Again, this proves that it is the functionality of the mac/program.
Beyond this issue, this document has crashed my Word multiple times when saving. Many other have reported the saving issue and also this scrolling lag issue. This is extremely frustrating and I would really appreciate if someone could let me know what the issue is and how to solve it.
I have tried the following fixes:
- Reinstalling Word
- Turning off transparency and increasing contrast
- Opened document with friend's Mac - issue persisted on their Mac as well.
- Copied information in a new document and saved it. Same problem persisted

Media Queries: Works on Mac but not Windows

http://www.sandiegohomegrown.com/testSDTG/
I have been coding this site on my Mac and it works with Firefox, Safari, and Chrome. I fired up the old Windows machine and it doesn't work with Safari, Firefox, or IE10. It just ignores the media queries completely. This has to be something really simple but I am baffled. Help!! Gary

Alt attributes on images are not significant for rendering. Did you fix the duplicate ID problems? Those are important.
Windows OS doesn't ignore media queries but some browsers will if they see code errors they can't reconcile.
Make sure IE is NOT running in Compatibility Mode which is practically the same as IE7.
If you want to ensure IE always opens in standards mode, add this meta tag to the <head> of your HTML pages.

Can stream music to Airport express from Mac, but not windows

I set up an Airport express for music streaming from a pc at my uncle's, and he used it without issue for 1-2 years. It suddenly stopped working for him, and was flashing amber. I was unable to configure wirelessly, but finally configured it with my Mac and an Ethernet cable.
We are able to stream music to it now, wirelessly, from my Mac. But neither his windows 7 pc, nor his windows 8 pc can stream to it. The airport does not show up on iTunes on either computer. Also, airport utility on the pc does not see the device.
I have tried everything I can think of: different settings on the airport, disabling firewalls on the pc, etc.
Is there a way to get this working for him again?

Bump again.
I'm also running into this problem. I have an Actiontec MI424WR and an Airport Extpress A1084.
When using WPA or WPA2, the AE can't seem to connect to the Actiontec. Has anyone found a solution to this?
Side note, I had been using a Netgear WNDR3800 as a wireless access point plugged into the (wifi disabled) Actiontec. In this configuration the AEs connected fine, but my network performance was pretty awful. In trying to troubleshoot, I'm removing the Netgear device from the picture to simplify. Now that I've enabled the wifi on the Actiontec, all my other devices (iphones, ipads, computers) connect fine, just not the AE's.
Thanks for any advice.

Quicktime File Crashing Both Quicktime App and Finder in Mac, but Not Windows

Hi,
     I have a drive full of Apple ProRes Quicktime files. Almost all of them play perfectly, except 2. Those 2 files have played in the past, but I've had problems with them. They've come back to functionality in the past, but now they are not working again and I don't understand why.
     Whenever I go to open the files with Quicktime Pro 7, Quicktime X, FCP 7, Adobe Premiere or Adobe Media Encoder, I get the spinning beach ball and not only does Quicktime crash, but the finder crashes as well. If I go to restart the finder, it never comes back online and I have to restart my late 2011 macbook Pro.
     I've tried repairing permissions and on the Macbook Hardrive and have used Disk Utility and Disk warrior on the hardrive containing the 2 quicktime files. Nothing has solved the problem.
     At first, I thought the Quicktime files might have become corrupted, but I installed Windows 7, using bootcamp, on the same macbook, hooked up the external hardrive and was able to play the quicktimes perfectly in Windows with quicktime 7 (not pro, because I don't want to buy it just for windows). So, there is some sort of incompatability between these two quicktime files and my Macboook.
     Does anyone have any ideas as to what could be going on?
-Scott

If you are on Windows Vista and trying to write something to
"Program Files" or its sub folders, write will not end up in the
right place as "Program Files" is protected. What ever you write
might go to a virtual store location. If that's the case try
writing to app storage folder.

Music stable with mac, but not mobile devices?

I recently got a new sound dock and got a brand new airport express with it so I can control the dock from anywhere in the house.
After setting up the airport using our Macbook Pro, I started streaming music perfectly fine from iTunes on the mac. To kind of show off the new toy to my wife, I started streaming music using my iphone 5. The music was cutting in and out like crazy. I changed to her iphone 4S and it continued to cut out like crazy. I even pulled out my oldschool ipod touch, and it continued to cut out.
So I am trying to figure out why there doesn't seem to be any issues whatsoever using the airport express from my mac, but all of my mobile devices have intermittent issues?
All devices have the most updated software that I can find.
The only thing I can think of is the connection to the network is weaker on the mobile devices than it might be on the macbook? They are all using Wi-Fi to my home network. So going by that, the aiport/dock/macbook all seem to have it figured out perfectly so something is working.
Am I missing some setting that is causing network lag on the mobile devices but not the mac?

The single biggest mistake in your analysis is assuming that if Windows (or a Wii or an iPhone or whatever other device) can connect, your router is not to blame.
Though devices are designed to standards, there can be errors in implementing those standards or even simple software bugs that come into play.
The example I've used over and over again is say there is a bug where when the router is asked to add "2 + 3" it answers "5" but when asked to add "3 + 2" it answers "6."
If Windows only ever adds "2 + 3" but Mac OS X adds "3 + 2," it's not Apple's fault the router is incorrectly responding "6" in the later case.
But let's start with easier questions:
1) Are you sure that no proxy is being used if one shouldn't be, and vice-versa?
2) Are the DNS addresses shown in your TCP/IP settings the same regardless of whether you are connected via AirPort or Ethernet?
3) Could there be some interference in the area you are using your Mac? Recall also that Mac and Windows PCs use different antenna designs, so what interferes with one may not affect the other.

I-pod touch works on a Mac but not a PC

Please help! My I-pod touch works on a Mac but not a PC. When hooked up to a PC, the device is not recognized in I-tunes message, says I-pod in recovery mode and to restore, after checking update and restore, receive unknown error message (9). Have tried unistaling and reinstalling I-tunes, using different USB ports, creating new user, restarting computer, using different PC, and trying to reset by holding sleep/wake and home buttons all to no avail, very, very frustrated, everything is fine on a Mac!!

I have CA Internet Security Suite Plus 2010, version 6.0.0.264.
I was wondering about that one in particular.
Try configuring you CA as per kalda01's instructions in this post:

(Sometimes switching the security software off doesn't help, but doing the configuration does help. Not sure what's afoot with that, but it has happened with other security-package problems with iTunes in the past.)

If time machine puts all of my photos onto my external hard drive using time machine, can I then delete the photos from my computer but view them again from the external hard drive? Basically, can I free up space on my mac but not lose years of photos?

To add to Niel's comment bear in mind that if you have a backup copy on an external HD and later delete the orignals on your Mac HD you will then only have one copy - so no backup.
If the pictures are precious you should have at least two copies, and ideally another copy kept off site,

I can connect to MAC but not my PC

I have a new Nano, that connects to Mac but not my PC. When I try to connect to PC it says "iTunes as detected a Macintosh formatted iPod. You must restore this iPod before you can use it on Windows."
How can I get my Nano to work on both?
Thanks!

Windows cannot read a Mac formatted disk.
You need to Restore on iTunes for Windows and it will then work on Mac & Windows.

Map Widget - Works on Mac but not in Author

OK, I'm a nube when it comes to Dashcode just so that's out there. I managed to build a custom map widget with Google Maps. The widget works perfectly on my Macs but not in Author. In Author the default place holder remains empty. If I click "edit HTML" I get the Google map, but it's just a generic USA, not the one I created w/ places. Also iBooks refuses to import the book to my iPad until I delete this map.
Do I need to do something or insert special code in Dashcode to make this widget "Author compatible" or are map widgets not allowed?

jfk0404 - I believe that what you're referring to as the "unattractive cartoon-like figure in the widget" is actually the placeholder image for the widget as it appears inline on the page. Once you click that cartoon image the actual widget takes over full screen and loads the html content displaying a functional full size google map.
To replace the cartoon icon you have a few options. The first thing to do is create a new .png file to represent your widget as the placeholder image enticing your readers to click to open the full screen widget and load its dynamic contents. Perhaps a screen grab of your map would be a good idea?
Easy:
Drag your brand new .png image from the Finder into your open source iBooks Author file dropping it on the cartoon image. Done.
More Complex:
Right click (control-click) on the xxx.wdgt file that downloaded from http://classwidgets.com and choose "Show Package Contents." A Widget file is really just a special folder bundle with a .wdgt extension. In there you will find the Default.png file. Highlight the file and press the space bar to see a preview in the Finder's QuickLook feature. That's your cartoon image. Now replace that file with the one you created above. Done.

Movie works on mac but not PC...help!

Hi!
Hopefully someone out there can help me...
I am trying to make a video play on a website that I designed. The video will play on a mac, but not a PC. When the user clicks on the link, the video (.mov) should start playing in whatever media player that computer has installed, either quicktime or windows media player. It isn't working on a PC. Maybe if I convert the video file to a windows media file or to a file that is easier read my a PC it would work? I don't know how to convert quicktime files into .wmv files.
help!!!
if you want to see the video, click on the "reel" link of www.williamday.net, then click on "reel" again in the middle of the page.

The problem is your page code (or lack of it).
You are directly linking to the file and bypassing any browser plug-in.

Link works on mac but not on pc

Hi -
I am trying to insert a jpg into a dreamweaver file.
I then upload the html file along with the jpg to my server in a folder called "layout"
So the url is: http://www.mysite.com/layout/test.html
The link works on mac, but not on pc's.
Any idea why?
Some links work on pc's like this, and others don't.
Thanks- It's driving me crazy!!

The link is not correct....you have it listed as" mysite.com", which I assume is where you are to insert the name of your url.

Web graphic links work on Mac, but not PC

I have two websites. The old one is DogToysAndTreats.com. The new one is FunStuffForDogs.com. I need to change the home page graphic on both of them to point to my shopping cart pages. I have done this and published the changes on both sites. It works on my Mac but not on my PC.
On www.funstufffordogs.com, the graphic at the top with the bulldogs is supposed to link to http://store.funstufffordogs.com/storefront.aspx. Same thing on www.dogtoysandtreats.com. It works on my Mac in both Safari and Chrome. On my PC, it doesn't work on IE, Safari or Firefox. (BTW, I haven't worked on any of the other links until I can figure out how to do it properly.)
I don't get why the platform has anything to do with it.
Lisa

Looking at your source, the problem may be that the images refer to an external server link from the one actually hosting the website page. Whenever you try to mix servers on a single page, you depend on the network connectivity being reliable to all the servers simultaneously. This can be as much a problem on a Mac as a PC. Sometimes routers have bad router tables, or internet providers do, and this can cause issues for multiserver websites. Using on your router & network settings an OpenDNS DNS server can help:
