6500 is the suggested choice for photo editing for use on the web, lower (5500) if printing. 7500 is too high

Again in Windows , the folder views are not colour managed. I would suggest you avoid any folder or preview mode views unless you know 100% it is colour managed. View only in Lightroom or some other managed software.
What exactly is "preview" ?

As an example of how colour management can fall apart I can tell you my discovery using Windows 7
When i got my wide gamut monitor I profiled it. All good. As long as I view in a colour managed application: firefox; photoshop; Lightroom; any image will be displayed correctly whether tagged sRGB or AdobeRGB. Now outside of those applications if I simply click on an image file it will display in the default Windows Photo Viewer. Which must also be colour managed as they display correctly too, unless I select "slideshow" in the Windows Photo Viewer. Now the pictures display in full screen and are clearly not colour managed as any sRGB photos have oversaturated colours. The same problem applies to the screensaver option. So if I want a picture to be part of my screensaver collection I need to make sure it is tagged AdobeRGB and it displays correctly.
I think your problem may not be too different from this.

If your jpeg image is tagged sRGB it should look pretty similar on your Wide gamut monitor and your mac airbook as long as you are viewing both in a colour managed application and both screens have been profiled. Perhaps worth checking the settings of Lightroom on your mac, and your mac itself to see if there is a colour management setting that is not right.
Have a look at this website PHOTOSHOP COLOR MANAGEMENT TUTORIALS Adobe CS CC Photoshop Troubleshooting Professional Photo Shop Training WorkFlows It has a load of stuff including rollover test images which you can use to determine if there is a problem with your settings. You need to be looking at the website in a colour managed browser such as Firefox where the colour management has been set in "about:config" to gfx.color_management.mode Value 1. There is a page on the website that explains this.
Also try this, upload your jpeg to a hosting site like Flickr, then view the image in a colour managed browser on both screens.

That would be true for any untagged file or for any AdobeRGB tagged file. If you have a sRGB tagged file you should notice less difference.

You also need to take into account the colour space profile of the files you are viewing, and whether whatever you are viewing them on is colour managed. Do the jpeg files have an embedded colour profile attached ?
Lightroom has a default colour space of Adobe RGB 1998 in the library and ProPhoto in the editor, but it will honour and display correctly any file that is tagged with a colour profile. Untagged files will be displayed differently.
When you work on a new edit from a RAW file for example, you may see much richer colours because of the Wide gamut editing working space (ProPhoto) and the wide gamut of your monitor (Adobe RGB 1998). But if that file is saved as a jpeg with sRGB colour space you may lose some vibrancy.
Do you have Lightroom on your mac too ? If not, are you viewing the file in a colour managed application ?

Also make sure you have no direct room light shining on the screen. A subdued ambient lighting is best for profiling the monitor. Also having your monitor brightness up at maxium is probably not the best way to start from. Check with the Spyder instructions. I use a Spyder as hardware, but use the screen manufacturers own calibration software (Eizo) which can adjust monitor brightness during the process. I think I start with about 50% brightness.
You have a AdobeRGB monitor so calibrate to that, not a sRGB display.
