Does macbook keep a history of wifi connections

I was wanting to check when I last used a particular wifi connection. Does the Macbook pro log this information?

If you're running 10.6, I'm pretty sure any such log files get rolled over when either the weekly or monthly automatic maintenanace scripts execute.
If you saved the password to your Keychain, Keychain Access (Applicaitons > Utilities) may have recorded the password and saved the date.

My safari does not keep my history despite all the settings and adjustment i made to the safari preferences so as to be able to keep my browsing history. the browsing history is wiped out whenever i close safari.

i use macbook pro mid 2012, OS X mavericks. my safari does not keep my history desp[ite all the adjustments made to the settings at safari preferences. my browsing history are cleared whenever i exit safari. i dont know why. i want to try and re - in stall it . the safari is version 7.0.1. but i dont know how.

If you're having trouble making changes to files that are inside your home folder (represented by a house icon in the sidebar of a Finder window), or if you can't get changes to the settings of an application to stick, then please see below.
Back up all data.
This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.
I've tested these instructions only with the Safari web browser. If you use another browser, they may not work as described.
Step 1
If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. To do that, unlock the preference pane using the credentials of an administrator, check the box marked Allow user to administer this computer, then reboot. You can demote the problem account back to standard status when this step has been completed.
Triple-click anywhere in the following line on this page to select it:
{ sudo chflags -R nouchg,nouappnd ~ $TMPDIR..; sudo chown -R $UID:staff ~ $_; sudo chmod -R u+rwX ~ $_; chmod -R -N ~ $_; } 2>&-
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
You'll be prompted for your login password. Nothing will be displayed when you type it. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command may take a few minutes to run, or perhaps longer if you have literally millions of files in your home folder. Wait for a new line ending in a dollar sign ($) to appear, then quit Terminal.
Step 2 (optional)
Take this step only if you have trouble with Step 1 or if it doesn't solve the problem.
Boot into Recovery. When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open.
In the Terminal window, type this:
res
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password dialog will open. You’re not going to reset a password.
In the dialog, select the startup volume ("Macintosh HD," unless you gave it a different name) if it's not already selected.
Select your username from the menu labeled Select the user account if it's not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
 ▹ Restart
from the menu bar.

Safari does not keep my history. What can I do?

Safari does not keep my history so I have to re enter websites that I visit often but are not bookmarked. What can I do?

Do you have private browsing turned on? Settings>Safari>Private Browsing>On. If so, turn it off.

I can print from my macbook pro using airport express usb connected printer, however my iPad is looking for an airprint printer. Can I direct the iPad to the usb connected printer. Both macbook and iPad confirm a wifi connection through the airport exp.

You will need to install an App like Print Central on the iPad to try to print to the printer. It will allow you to print to most printers. Check with their support folks if you need more info.

When I bootup my Macbook my family's PCs wifi connections stop working !

Hi everybody, when my nephew boots up his Macbook (Snow Leopard 10.6.5) he can regularly surf the web through a wireless router. However the wifi connection on other devices (Windows Vista notebook PCs, Linux Pcs, Windows 2000 PC, Playstation 3 wireless, PSP, Xbox ecc.) stops working. When he shuts off his Macbook, wifi connection on Windows/Linux PCs etc. starts to work again.
I've had similar issues only with a wireless TV signal transmitter (working at 2.54 GHZ). When it is on, wifi connection is impossible, no matter what channel is selected (it has 4 channels).
What to do with my nephew's Macbook? I can see that every 10 seconds Airport is searching for wireless signals (the wifi led on the router blinks), but no other traffic is sent/received so I don't think it's a bandwidth problem.
Can Airport be shut off and can I connect to wifi router without airport using other apps or using a terminal (console) application (I use Linux and many commands are the same, i.e " iwconfig - ifconfig ")?
Maybe it's the transmitting power of MAcbook wifi device (too strong?). Can it be modified? I'm not a Mac guru... In linux there is a command, say "iwconfig wifi0 txpower 20mW " to tell the wifi driver to use 20 mW transmitting power on wifi0 device. In that Macbook the wifi device is called "en1"...
Many thanks in advance for good ideas..!

Many thanks for such a fast answer!
@ a brody
I have so many wifi devices (at least 17) I don't want to create a MAC address filtering rule for each one of them! I don't ever know if my router can accept filters on so many MAC addresses!! But I will try out your suggestion if I can't solve in other way.. Thank you!
@ J D McIninch
Thank you, I will try... However, my router don't need to be restarted to get online again: when my nephew shuts off his Macbook the wifi connection is all ok. How could it be that a routing table gets corrupted when the Macbook is on, and that very same routing table gets repaired as soon as the Macbook is shut down? I'm sure, however, my router is a pre-N one ( Belkin modem/router bought in 2004, 802.11 b/g 54Mb with 125Mb turbo mode feature always turned off for backward wifi compatibility)
Thanks

Why does my iPad often lose the Wifi connection?

Hello all -
Often when I am using my iPad at home (which is where i use it 95% of time), the WiFi connection will simply disappear - sometimes every 2 minutes of so. Sometimes, when I pull up the "Utility" screen from the bottom (sorry, don't know the correct name), and then unclick the WiFi connection, wait a few seconds, and turn it back on - the connection comes back. But that probably only works 10-30% of the time.
The way I can always make it come back is to go to the Settings app, click on Wifi, where it shows no connection. Then if I turn on WiFi, after a couple of seconds I see my network appear under the "Choose a Network..." section, and then a few seconds later, see it appear in the top section.
Does anybody know why this might be happening and what I can do to fix it?
Thanks.

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at
http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are drooping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
Some Wi-Fi losses may stem from a problematic interaction between Wi-Fi and cellular data connections. Numerous users have found that turning off Cellular Data in Settings gets their Wi-Fi working again.
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.

Does SAP keep change history for program variants?

Hi,
Does anybody know whether SAP keep change history for program variants, like it does for PO, Material etc?
If so, how could I get this information? If not, does it mean there is no way we could find the changes made to the variant?
Thanks
steven

Hello Steven,
I see that this is your first post to the forums here and I would like to welcome to SDN and BPX. I hope you will find these communities very helpful for learning and sharing information about SAP Products and Technologies.
Regarding your question, I think the best place to find the answer would be the ABAP Development.
However, being an experienced ABAP developer myself, I do not think program variants have change history. And yes, there is no way to retrieve the old values of the variants .
Regards.
Anand Mandalika.

Does Sync keep a history of over-written files?

Hi,
Does the mobility sync function keep a history of over-written files somewhere? Does it copy them to a trash-like place that can be recovered? or does it just over-write the older file? I have a problem where my Entourage database file did not load properly on the client machine, became corrupted, and has over-written the server version of the database.
Thanks,
Dave

There is no backup, just a sync.
As for entourage. The whole database thing is a joke.
If you have a database that is 1GB
and get 1 new email.
The system sees that the 1.1GB file is brand new and overwrites the old.

Macbook Pro 10.7.5 Wifi connection dropping

For the past few weeks I have been encountering a problem with my macbook pro connecting to the wifi. Every so often my mac will "disconnect" from the wifi, however my mac will still show a full connection. In order to solve it this I can disconnect from the wifi and then reconnect and I will be able to use the internet again without an issue. But within 20 minutes the problem will come back again. I have tried resetting my computers wifi preferences, I have switched the channel my router is using, I have even switched the router from 2.4ghz to 5ghz to no avail. I have seen where other people have been having the same issue as me but so far I have not seen anybody offer up a solution that works. Does anybody know what is causing this or how to fix it?

We are still having issues with this, is there anybody out there who has a solution or has encountered the same problem?

Does MacBook Early 2008 support 5GHz wifi?

Hi everybody,
I just want to purchase the new AirPort Express dual band to improve wifi domestic network, but I don't know if my MacBook is using 2,4 or 5 GHz....

I don't think this model does. Only 2.4GHz is supported I think.

Does the iPod Touch Bluetooth require wifi connection?

I have an iPod Touch 3rd generation and plan to upgrade to the 4 this winter but if the Bluetooth does require wifi I'll probably choose the iPhone. The reason I ask is because I want to get these Bluetooth earbuds since I'm sick of the wire. But, if the iPod Touch BlueTooth can't work while I'm out then what's the point in staying with just the iPod? I prefer having just the iPod but I am seriously that sick of the wire that I'd get the iPhone.

BT will work fine without wifi.

Why does Safari keep saying "it can't connect to the server" every time I try to access any sites?

I have the latest safari update for os x, which was working perfectly fine up until 3 days ago. Everytime I would try to access any site, safari would tell me it couldn't connect to the server, and I would have to refresh the page at least 5-10 times until I can access the site. I checked my internet, and it seems to be running perfectly. I also tried using Chrome and it had no problems accessing sites, too, so I know it's not my internet. :/
Is anyone else having the same problems?

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you boot, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, reboot as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.
