Multi tasking on macbook air
hey
we all know that macbook air got wireless 802.11n which is d best available in market right now. but after reading through the specs of MBA, i came to know tht we need to hav a lot of things extra with it like time capsule, superdrive etc...
now my question is can we simultaneously browse the net on wireless, run time capsule and also use remote disk ??? i mean run 3 different things at d same time through the wireless card ????????????
One can, I don't know if you can.
The setup you described would require the TC to be either directly connected to the internet or to be set up as a repeater for your existing router. Then it's necessary that the computer, which disc you wish to use, is reachable from the TC (i.e. by being directly connected to it or connected to the router which the TC repeats). Then you only have to connect the MBA to the TC and it should work.

Can't use multi-touch in macbook air on windows 7
i just install windows 7 via bootcamp and install the bootcamp windows support.
everythng seems fine, but the trackpad....
I can use scroll up and down, but i can't tap to click..
and i can't find the bootcamp in windows 7 start manual.
anyone can help me?A Chrome extension is out which enable Bootcampers to swipe back/forth with two fingers for pages. You can get it here:
https://chrome.google.com/webstore/detail/mgegfjnccpnkdppohmfgnjalkediapkc
Or search for it yourself:
Swipe Gesture
In google addon store.
All credits goes to antimatter15.com for creating this. It's still at an early stage, but very useful indeed. And as seeing that swiping back/forth is one of the most used multi touch features (at least to my experience) this addon is a godsend. Also has no problem with people running virtual machines, as the addon can simply be turned off. -
I have a MacBook Air 11" and it don't recognise my LG Slim External Super Multi DVD Rewriter
Hi , my MacBook Air 11' don't recognise my LG Slim External Super Multi DVD Rewriter (Model GP08LU10). Can anyone please help me?
Just wanted to conclude by saying that I did go to an Apple store and after supplying proof of purchase and verifying the warranty etc, I had my MacBook checked out by one of the technicians who (after finding that my machine was immaculate bar the sticky keyboard of course) they replaced the entire keyboard within a week.
I was so happy with the helpful and prompt service and am now so happy with my new silent keyboard!
Also wanted to add that the young guy who told me at the iStore that he doubted Apple would support this and guessed Apple likely say it was due to user damage was being a tool, and he was obviously assuming that I had done something wrong to break my keyboard.
This was my first Mac purchase and I was delighted to find that the support is genuine and not just a rumor... I have since gone on to purchase an iPad2 will probably buy the iMac too once my trusty PC needs replacing. I was never a PC hater and got on well with windows, and was actually reluctant to make the change - but so far so good :)
Thanks for all the help! -
Macbook Air constant kernel task and random reboots problem
Hi my Macbook Air has suddenly started playing up after being fine since purchase. While engaged in photo editing in Photoshop a couple of days ago the fans were screaming flat out (not so unusual) but I had a look in Activity Monitor and noticed an ongoing Kernel Task, I never usually see these but now they always seem to be running hogging (at the moment 608 MB of) memory. Now today the machine has shut itself down twice too something that has happened once or twice only in the last two years . I reset the NVRAM but the kernel task is still running.
Any clues what to do next? Could it be 10.9.2 related?
Thanks
SimonThe kernel_task (pseudo-)process is always running. It should not, however, be using more than a few percent of the CPU. Is it?

No multi-channel available with HDMI output in Audio MIDI Setup on Macbook Air mid-2011 !!!!!!!
Hi everybody !
I am currently facing some problem with seting up a surround sound system.
I looked everywhere on the web but i couldn't find any proper answer to this problem.
To sum up, i want to have a Dolby Digital or DTS surround sound when i'm playing a movie (with an AC3 audio track obviously).
I have a Macbook Air 13" Core i7 connected to a SAMSUNG Plasma TV via an iWires thunderbolt -> HDMI cable (bought on the same time as the MBA). This TV is connected to an amp via an optical cable and this amp to a 5.1 system.
When i am going to Audio MIDI Setup to configure the HDMI output, i cannot select any multi-channel option, only stereo !!!!
Is someone has any idea how to solve this problem ? I am struggling a lot and spent hours on that without finding any solutions !
Thanks a lot for your time !Hello ckkzzzle,
I was looking into the issue you are describing and think I have a great article to help troubleshoot it. The article is called Apple computers: Troubleshooting issues with video on internal or external displays found here: http://support.apple.com/kb/ht1573.
Start here, and work your way down as needed:
Check connections
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
If more than one video adapter is in use—or "daisy-chained"—troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
All the very best,

Apple MacBook Air 2011 - powerful enough for most tasks?
I want to buy the 2011 model of MacBook Air 13” 128GB, but I have some questions for you guys, would appreciate it if you experts have answers:
1) I'm currently on a two year old Acer Aspire 6920G laptop with 17”, Windows 7, Core Duo 2 (T5750 @ 2.0 Ghz) and 3 GB RAM - will my new MacBook Air feel one million times faster to use?
2) Can I later (easily/cheaply) upgrade the MBA's RAM to 8GB?
3) I mostly use web browsers, office software, IM programs, media players etc., but I will also use it a lot for electronic music making (with Ableton Live and virtual instruments/effects) and DJ’ing (with Avid Torq). I almost never do any heavy duty image work, and I rarely code/edit video - will the MBA be fast enough for the things I do most often, or do I have to get a MacBook Pro?
4) How often does the fan start up? And when it's on, how much noise does it really make when it approaches 6500 RPM?
5) I read that with Lion the fan is running more than with previous OS'es - can this really be fixed with booting in 32-bit rather than 64-bit? And what will that entail for the CPU power/battery longevity/software compability?
6) Is the graphics adapter in my current PC (nVidia GeForce 9500M GS) much more powerful than the MBA's Intel HD3000, or is it almost the same now?
7) Is it easy to run Windows XP or 7 in Boot Camp? I have a few Windows programs I'd like to continue using.
8) Should I alternatively use a few more bucks and get a MacBook Pro with SSD-disk? Is that less "locked" and more compatible with what might happen in the future, technology-wise?
9) Is it possible/cheap to switch the English keyboard to a Norwegian one next time I'm visiting Norway?
I have to make a purchase of a new laptop soon, so I'd GREATLY appreciate any answers. Since I have had software- and hardware problems with every PC I've ever owned, I frankly do not trust them anymore. So here we go then - Mac!Let's see if I can help
1)The i5 Macbook air should be considerably faster than your previous laptop. Mostly because of the SSD and the i5 processor.
2)I'm not sure about the latest macbook airs, but previous models have their RAM modules soldered to the Logic Board, I don't think you can upgrade the RAM at all.
3)The MacBook Air might be fast enough, but Just, I would go with a Macbook Pro, mostly because it's easier to upgrade.
4)It will kick in several times but rarely at full speed, and it's not that loud. Would recommend a macbook pro for cooler running.
5) I didn't notice any difference between Lion and Snow Leopard regarding fan activity. Lion is a 64-bit only system, there is no way to boot in a full 32-bit environment. Compatibility can be an issue with some software, ie. traktor users have been reporting problems with external hardware running Lion, but updates will fix these soon.
6)They are at comparable levels, the Intel HD 3000 might even be better at some point. It's much better than the 9400m that older macbook airs had.
7)Yes, as long as you have the optional super drive to install it.
8)Yes, that would be a better idea.
9)I don't think so, never heard of people swapping keyboards on Macbook Airs or Pro's.
I'd buy a MacBook Pro if you are planning to keep it for long. It's more powerful, more upgradeable and runs cooler and quieter than the air.
Hope you get your mac soon! -
What's the best multi-monitor solution for macbook air?
I am trying to create a 3 monitor setup for my MBAir 13" Late 2011, and also a 2-monitor setup for my wife's 2013 11" MB Air. What is the best solution to accomplish this? I have already narrowed down my monitor selection to the Dell Ultrasharp U2414H with the micro-bezel.
What should I use to connect the laptops to the monitors? Matrox Triplehead2Go DP edition? Any experience would be greatly appreciated here!
Thanks!
RichThere are no good cheap solutions due to Macbook Air's only supporting thunderbolt 1 regardless of what your User Manual may say. U2414H is not capable of daisychaining on Macbook Airs', only 2013 Macbook Pros and later. Your Two choices are Lg 34um95 and daisy chain those with thunderbolt cables or Apple's Thunderbolt display. If you dont care about quality of your second and third monitor external (meaning tearing and slow frame rates). Get a USB 3.0 to (HDMI or DVI) ( Your prefrecnce between HDMI and DVI (Make sure that the device you pick is Mac Compatible)) and a usb 3.0 hub with an AC outlet of preferably 12V, 5V may be too little. for your second and third external monitor and a thunderbolt to (HDMI or DVI) for the first monitor. USB 3.0 Does not have great video performance in viewing your screens. Watching Movies or Playing games using USB 3.0 will result in video tearing. I only recommend using the usb 3.0 adapter screens for Typing or web surfing.
Basically
1st external monitor( Fast Normal Framerates and no Video Tearing) <----Thunderbolt to HDMI/DVI adapter
2nd and 3rd external Monitor ( Slow Framerates with Video Tearing)(USB 3.0 to HDMI/DVI) connected to USB 3.0 12V Adapter Hub connected to 1 macbook air usb 3.0 Port. -
Why doesn't multi-touch scrolling work in my Macbook Air?
I just upgraded my (first edition) Macbook Air to Lion. Unfortunately, I've found that two-fingered scrolling does not work in Mail and Safari (and probably other apps as well). When I try to scroll with two fingers, the cursor won't move at all. Other two-fingered gestures, such as zoom and pinch, work fine. Any ideas what's wrong? I checked the system preferences under both Trackpad and Keyboard and didn't see anything useful. Thanks!
Never mind! After I posted this, the relevant answer appeared in the More Like This column. (Funny that I couldn't find that answer before I posted the question.)

Ok,
This is my first post to this forum.
I have a Late 2011 i5 Macbook Pro. I used this last year during college but the weight was just unbearable. I have decided this year to upgrade to a Macbook Air. Here is my question.
I am starting uni and will be studying Nursing and so I will not be using any heavy software or progaming etc.
The only thing I will use is Office for Mac and browsing. I normally keep around 15 browser tabs open whilst I research.
I also like to download so I would also like Vuse on my Macbook too. I own an external hardrive and so memory isnt a big deal (unless it makes a difference to the performance of the mac itself, Sorry im not great with this stuff)
Do you guys think the base model of the 11" Macbook Air (1.3ghz, 4GB ram, 128GB SSD) will be enough for my needs or do you think I would need to custom build it (1.7ghz, 8GB ram, 128GB SSD)?
My boyfriend thinks for what im using it for the base model will be fine but I dont want to get it to find that its not enough as my main concern is lag but I also do not want to pay extra for something which isnt going to be fully used (ie my current Macbook Pro).
For those of you who do have the 11' Macbook air, how are you finding it? Also, this will be my main computing device, I am selling my Pro but am thinking of buying the wireless keyboard and trackpad so I can connect to an extenal monitor whilst im at home.
Thank you guys in adavnce for any answers.I too have a 2011 mackbook pro and I also have a mid 2012 mackbook air 128 gb ssd and 4 gb ram , I am probably goint to sell the pro because I just don't use it anymore . If you intend to do heavy multi tasking 8gb ram as suggested by a previous poster might be worth the extra money.

Some advice - buying a MacBook Air
Hi,
I am planning to buy a MacBook Air (13" version), and have some questions which I would like some help!
1. Performance/Upgrades
I am trying to figure out whether I should get the Processor (i5 to i7) and/or RAM (4GB to 8GB) upgrades - is it worth it, for me?
My day to day usage is quite regular - Outlook, spreadsheets, writing, browsing, streaming online videos, a few flash games here and there. But, I do multi-task heavily, in that I can have large numbers of files/programs/browsing tabs all open at the same time, flicking between them to get things done quicker. On a few odd occasions, I do use more intensive programs such as photo editing, web design, video editing etc.
From the research I have done I believe that a faster processor would only really benefit me in some of the more intensive tasks such as a video conversion. Now I know a professional video editor would the quickest conversions if they are doing it all the time, but for me, because this sort of task is quite infrequent, I can handle it taking an extra 10 minutes to convert something. What I couldn't deal with is for these applications to be slow and draggy in their overall usage.
For the RAM, I guess this would be a lot more useful for me, in terms of the multi-tasking applications and files? My existing laptop (albiet old and cluttered) is a Windows 7 with Core i5 dual core and 4GB ram. I have sometimes found when opening significant numbers of tabs, it tells me I am out of memory, or the application windows will start failing to load/turning black screen etc). Things take a long time to open. This sort of thing, I find annoying!
If I get either upgrade it means spending £1050-£1150 on the Apple Store. If I don't need the upgrades, I can get hold of the standard MBA for just £850 from Tesco, and that's quite a saving that I would appreciate at the moment... but only if it doesnt result in a lower performance that I would notice.
So this is the first question - what sort of day to day tasks would a faster processor and/or extra RAM benefit, and would I likely notice this? What about for the heavier applications? Do you think from my comments above that I should bother with either?
2. Using Windows apps
I've seen that you can run Windows programs on a Mac through Boot Camp or other software like Parallels. This would be really useful for me as I do have the odd program which is Windows-only and I would still need to use. However I have also been reading that doing this would significantly reduce performance/battery life on the Mac.
Does this mean that the Mac would have reduced performance/battery ALL of the time - even when Windows isn't being used, or does it just mean for the duration of time that you're actually logged into the Windows OS?
I can deal with slow performance whilst using Windows applications, as I don't intend on using the MBA as a full time Windows machine - but I would not want my battery/performance to suffer for the rest of the time when I am just running Mac stuff.
Any thoughts or experiences with this? And any tips on the best and most cheapest/efficient way to run Windows programs on a Mac?
3. Other crucial tips on switching?
I have used Windows for 15-20 years and never had a mac, but with the new Windows 8 being completely rubbish especially without touch screen, I think now is a good time to make the change and give Mac a try.
I've given the topic a good bit of research and have an idea of what will be different between a PC and Mac, but if you have gone through "the switch" yourself and think you have any particularly good tips from personal experience - such as things I might find difficult in getting used to or things I will have to sacrifice, or things a Mac won't do that I could have done in Windows etc - then let me know so I dont get any nasty suprises
I realise this is a lot of questions and info but having read lots of reviews and articles I'd like to just get some Apple user feedback - straight from the horses mouth - as this is kind of a big step for me to make this change and I dont want to spend all that money and regret it!
Thanks so much!
DanielleHi,
Thanks for your reply.
>>Running bootcamped Win7, yes power consumption is more, a lot more,....indications are no.
Sorry, can you clarify on this one - do you mean the power consumption is more DURING the use of Windows, or ALL of the time (even when using the Mac as normal with OSX).... also what did you mean by indications?
>>From the parameters of what you say your use would be, Id recommend the I5 with 8gig of ram. the 12 hour >>batt. life is only rated for the 13" on the I5, ....not the I7.
Sounds like my first guess was about right - and good point about the battery life - as that is something that's quite important to me!
>>The "switch" is extremely easy. Ive seen grandmothers switch to a MAC and have its 'everyday use' >>conquered in under a week. So, you should have no worries, its extremely user friendly, no worries of virus, >>etc.
Glad to hear I've done more research and already seen a few features I can see myself preferring a lot more to the Windows system!
>>As a former computer repairman, Ive owned nearly 200 diff. laptops (many were free, or Franken-computers >>built from parts) and I can honestly say the Macbook AIR is the finest piece of beloved hardware Ive ever >>owned by a mile.
>>Many people incorrectly see the THIN nature of the Air and incorrectly conjecture its "less than" a full laptop, >>but the contrary is the case.
Nah, I don't associate size with performance - especially these days, everything is getting smaller. My concerns are really just about whether to upgrade for extra performance, and using the OS - once I have those nailed I am pretty cofident the hardware will perform well.
>>Additionally the AIR is the only Mac that has 802AC wifi, new Haswell cool-running processor, and extremely >>long 12 Hr. batt life on the I5 13" configuration.
Yeah that battery life is one of the big sellers
Cheers for the tips,
Danielle -
Logic Pro on a Macbook air 11''
Hi, the Macbook air 11" has a 1366x768 rez, and the minimum required for Logic 9 is 1280x800, according to the documentation and Apple's website. Has anyone tried Logic with lower resolution than required? Will it work or will it make access to some parameters impossible? The puzzling part is that you can order the 11" air with logic express pre-installed... Any thoughts?
-FredHi Everyone
I recently purchased a maxed out 13" MacBook Air and very successfully running Logic 9 on it. I posted my summary on Gearslutz a little while ago, but I'll copy it here for your information:
Just thought I would give a short report of my experience using Logic Pro 9.1.3 on a MacBook Air (late 2010). It is the 13.3” 2.13GHz, 4Gb memory, 256Gb SSD model.
First of all, I am not intending to use it for any kind of audio recording. I’m not saying that the MBA couldn’t handle the task; it’s just that I have no need of it. I want to be able to sketch out ideas in a hotel room with minimal equipment (in other words, a laptop, a two octave keyboard, a pair of headphones and me).
First of all, I tried the Logic Pro Multicore Benchmarktest several times. It gives a solid 17 tracks, which I am very happy about. My previous laptop, a MacBook Pro 15” (mid 2009) 2.66GHz 4Gb, could only get 20/21. So doing the maths, I was only expecting about 16 from the MBA anyway.
Secondly, I tried several instances of Omnisphere (my main sketching VI). I used three instances, each running the “Astral Visions 1” patch, another three instances, each running the “Bandpass Trancer” patch and finally another three instances, each running the “Brazillian Bandpass Thipper” patch. That’s 9 separate instances of Omnisphere and there was still processor to spare.
So feeling brave I tried adding some MULTI instances of Omnisphere. I managed to add 4 (“Fandrum Club Groove”, “Techno Land”, “Balaphonic Dance” and “Vox Continental Arpeggiations”) and although the processor bars were both peaking into the red, the project never once stopped (I left it running silently for an hour). Activity Monitor showed an average of 135% CPU being used with over 1Gb of memory still free. The fan does come on and there is a slight noise but nothing very noticeable.
Logic looks good on the 1440 x 900 screen and even though the pixel density is much higher than on the 15” MacBook Pro screen, everything was still easy to read and use.
So to summarise, I am a very happy MacBook Air owner. Obviously it’s nowhere near being a desktop replacement, but that’s not I was looking for. I wanted a lightweight machine that could run several VIs easily and that’s exactly what I have. If I sound a little bit smug, it’s because I am! -
Do I really need an optical drive (external) for my MacBook Air to install Win 7 with Bootcamp?
I have a Macbook Air (11" if it matters, the tiny one) that was purchased late last year, new. I would like to install Bootcamp and be able to boot into Windows 7, 64 bit. I have a Windows 7 Professional disk, which I would have to find an optical drive of some sort to install. The Boot Camp PDF guide doesn't mention the use of any kind of USB bootable install. In fact, I often see (on Apple support pages) that an external optical drive is required for Macbook Airs.
Is this the case? If not, does anyone have any advice on how to make sure this goes smoothly? I'm a bit of a newbie to Macs. Thanks.
(Note: I didn't select my OSX operating system, but it's been updated regularly.)Thank you Rysz, but (if you scroll up & read my original post you will discover) I don't own my new MacBook Pro...yet! I'm just researching ahead of time to help me make the decision. The customized MBP I have saved in my cart is over $3000 (incl the 3-yr support plan). So it's going to take me a little bit of research before I decide or before I can really justify the purchase.
I just wanted to be prepared for all the inevitable technical / learning-curve headaches that I will experience IF I take the plunge. And as everyone has experienced, when you're new to and making your first purchase of a different technology, and you don't know what to expect about a purchase, you ultimately get it home, set it up and find it didn't come with all the necessary interface devices, converters or cables, etc. And of course the online purchase procedure wizard doesn't tell you or ask you what else you will need if you want to perform a specific task.
But I'm sure (if) once I do make the purchase, I will definitely be back here to pick everyone's brains! These communities are fantastic. Thanks again! -
ArchLinux Installation disk doesn't recognize Macbook Air SSD[SOLVED]
I want to install ArchLinux on my new MacBook Air (dual boot), I made a dd of the installation iso to a usb disk. The usb disk can boot and run, but it cannot recognize the hard drive(SSD) of Macbook air.
There are three disk files in dev: /dev/sda /dev/sda1 and /dev/sdb
/dev/sda is the usb disk, /dev/sdb cannot be opened by parted and cannnot be mounted (it reports "no medium found") and I believe it is the sd card reader.
What can I do?
dmesg shows the following errors:
ata1: SATA max UDMA/133 abar m8192@0x93284000 port 0x93284100 irq 25

Macbook Air running extremely slow - kernel_task at 300% cpu usage
I purchased my Macbook Air roughly 15 months ago and it's performance has constantly been impressive since I purchased it - until roughly a fortnight ago. I came home from work one afternoon and it was running at a snails pace. I had recently upgraded to Yosemite though I'm unsure if this had anything to do with it. I had also recently installed FitBit software to sync to my new FitBit flex.
It has continued to run in this manner constantly since the problem began. It is ridiculously slow, every single request takes a very long time to respond. Logging in takes forever. When I click on an app to open it, the icon bounces for 30 seconds or more, and it's not a smooth bounce either, it's quite a jagged bounce!
I'm hoping someone is able to provide some advice, guidance or help. The laptop is no longer covered by the 12 month Manufacturer Warranty, and I did not purchase an Apple Care plan as no Apple product I've owned before has experienced issues like this.
This whole experience is killing me! I'm suspecting hardware failure and I'm just so sad that this could happen to the laptop I've loved so much since I bought it!
The problem:
The kernel_task process is constantly running at 300% or higher cpu usage, with Activity Monitor indicating the processor is being maxed out by a system task. Also, the laptop's fan is constantly running at full capacity - from the moment the laptop turns on, or wakes up.
What I think the problem might be:
As a result of many, many Google searches, it appears that this behaviour may be due to the Macbook Air thinking it is overheating - and I will clarify here that it certainly is not. It is cool to touch, always, when this problem occurs. (yet the fan is almost taking off!). As a result of the MacBook Air thinking it's overheating, it not only is running the fan at a very high RPM (confirmed with iStat), but it also is intentionally choking the system with 'simple requests' in attempt to cool the computer down. Apparently this is a built-in feature of OS X. The kernel has priority over user tasks, causing all user tasks to be granted a lower priority, causing the computer to run INCREDIBLY SLOW. Even as I'm typing this, I'm about two sentences ahead of what is showing on the screen!
Steps I have taken:
- Read widely across the internet with every possible relevant search term I can think of
- Downloaded iStat to see if any of the temperatures are too high (they all seemed fine..)
- Disabled Bluetooth and Wifi. (no change)
- Reset SMC (multiple times.., no change)
- Reset PRAM (multiple times.., no change)
- Drained the battery completely (2 or 3 times, no change)
- Install Windows 7 on BootCamp in attempt to bypass the issue (CPU usage was 100% constantly in Windows also)
- Uninstalled FitBit software (no change..)
- Uninstalled other software I did not need (no change..)
- Attempt to boot into Safe Mode / Recovery Mode (even in this modes, the same thing is happening)
- Repaired Disk Permissions
- Backed up all personal data
- Used the built-in Internet Recovery mode to format my Macintosh HD and re-install a fresh copy of OS X (Mountain Lion). (no change…)
- Re-upgrade to Yosemite (no change..)
I've downloaded EtreCheck and here is the output:

Dec 20, 2014, 02:15:38 PM Self test - passedHi,
I have an update so I thought I would share in case any other users are experiencing a similar problem.
I made an appointment with the Genius Bar at the Apple Store.
I went in and they ran a thorough diagnostic check on my Macbook Air and determined that the sensors were indeed faulty - several were providing no information "No reading" instead of providing a temperature. Thus, the Air was unaware of the temperature across multiple components.
Despite the laptop being outside the 12 Month Manufacturer Warranty, the Apple Store determined that it was covered under warranty through Australian Consumer Law - the laptop is now in for a complete repair under warranty at no cost to myself.
I couldn't be happier. -
