1) How to reduce MacBook boot up time? 2) Should I upgrade my 2008 MacBook to Lion? 3) How long will a 2008 MacBook last (after 4 years)? Thanks!
I have three quick questions to ask:
1. My MacBook (bought in late 2008, 2.4 GHz Intel Core 2 Duo, 2GB RAM, 160 GB HD, running Leopard/10.5.8) boots up quite slow. It can take a while to boot up and shut down.
Question: What should I do to reduce the boot up time?
I haven't done a clean up for a while, and am a MacBook newbie (after 4 years, still) for the tools. I think I need to remove some applications but don't know exactly how. Also I am looking for stuff like System Defragment / Compression (tools available for Windows OS) to tune the hard disk performance, if possible.
2. Sort of related to this slow boot-up time - should I bother to upgrade to Snow Leopard (pay $ 29.00) and then upgrade to Lion (another $ 29 ?) for some 250 new features that I am not exactly sure if I will need it (or my 2008 MacBook can handle it well)?
My friend has a 2011 MacPro which he let me use it for a while, so I think I am already using Lion, but frankly I can't tell much difference from the user experience (am just a very average Mac user!).
Question: Should I bother the money and the time (I heard the downloading and installation time for Lion is very long) if all I care is boot-up time?
3. One last question - How long can my MacBook last? Is there a way to find out the battery life? Any indication that my MacBook might be on the edge of its life cycle anytime soon?
I heard that typically the life for a laptop (PC or Mac) is 2 years. I am not a heavy user, and I guess that's why my MacBook is still alive after 4 years. But should I expect that to be failing any time soon?
Thank you!
I'll try to make it short but with your questios, might be impossible.
I own both late 2008 MB Uni with 2Ghz and a brand new late 2011 MBP 13 inch.
I have lion running on both Macbooks with no slow down or issues.
The late 2008 I upgraded to 8GB Crucial DDR3 Memory and 320GB Seagate Hard Drive. Total cost to me? $140 CDN ( i live in Canada ).
My MB Uni's battery has 1047 cycle count and I still get 3-1/2 - 4 hours of battery life depending on what applications I'm using.
As for typical life of a PC or MAC ( I own both ). The PC's life is shorter than a MB. I have a 4 year old Dell Vostro that I had to do a RAM upgrade so Windows 7 would run properly.
My late 08 MB had 4GB of RAM when I upgraded to Lion with no issues. i just decided to go 8GB because it was cheap.
A 2GB MB will boot up and run faster than a 4GB PC with windows 7.
Nothing is obsolete if you can still do your stuff on your MB.
To make it boot up faster, see what's loading on startup and take them off if you don't need them.

Yes.
Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard — Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
Snow Leopard General Requirements
1. Mac computer with an Intel processor
2. 1GB of memory
3. 5GB of available disk space
4. DVD drive for installation
5. Some features require a compatible Internet service provider;
fees may apply.
6. Some features require Apple’s iCloud services; fees and
terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service — this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
Lion System Requirements
1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
or Xeon processor
2. 2GB of memory
3. OS X v10.6.6 or later (v10.6.8 recommended)
4. 7GB of available space

Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.

I have macbook pro 10.5.8 can i upgrade to the Os X lion?
I have macbook pro 10.5.8 can i upgrade to the Os X lion?
apart from what is already known ( upgrade to Sno,purchase Lion or walk into a Apple Store, ask for a USB drive .. ) you should make sure you can run Lion. Not every Intel Mac will run it, and you need 2GB of RAM.
Double check that requirements before. -
Can i upgrade the new OS X Lion for free if i bought my MacBook pro 13" around Apr 2011 in store?
Hi eveyone,i just check online that you are entitle for a free upgrade to new OS X Lion if you buy a mac book pro from June to July 2011. Can i upgrade the new OS X Lion for free if i bought my MacBook pro 13" around Apr 2011 in store?
When it says on Apples website that it runs from june - july 2011, I seriously doubt you can get it for free when you bought it already in April.

How long does the MBR Battery last in years? Deciding factor on purchasing? Help?
I'm nearly ready to pull the trigger and get my first MBR 15 inch, but something keeps nagging. The Battery. THE BATTERY. Yes the battery is relatively nice, and one might think insignificant in the grand scheme, but IT'S GLUED INSIDE THE COMPUTER, and basically IRREPLACEABLE unless you pay some ridiculous cost, my guess is around $400. So how long is the battery expected to last? 4 years? No battery lasts 4 years. It's mind-boggling to me why Apple decided to glue the battery. After 2 years of moderate to heavy use of your MBR you're just expected to fork over $400 for a new battery? A NEW BATTERY?!!!!! Realistically how long will the MBR battery last before it gives up the ghost and has to be plugged in 24/7?
It is not "glued" inside the computer. And yes Apple offers a replacement program for $200 and under depending on the model for out of warranty:
http://support.apple.com/kb/index?page=servicefaq&geo=United_States&product=Macn otebooks
For in warranty for a defective battery, it is free:
https://www.apple.com/batteries/replacements.html
AppleCare can be bought at discount during the first year of computer ownership from:
https://www.lacomputercompany.com/cgi-bin/rpcart/featured.cgi?group=appcare
Just remember to register it after receiving the box, and keep all the material inside, including the registration number until you get your enrollment number.
How long? Depends on usage:

How to reduce the query execution time
hai all,
We have created query on Purchasing Cube 0PUR_C01 for
Purchase Order (PO) analysis for single vendor materials, but it is taking long time to execute (about 45 sec...).
In the above Query we have used the following things:
In Columns:
i) Exceptional aggregation for maximum & minimum PO Net Price using reference characteristic as Calendar Day.
ii) Minimum PO Price value we have multiplied with Actual GR Quantity for the calculation of Impact of Lowest PO Net Price.
iii) Number of vendors calculated key figure.
In Rows:i) Only Material
In Filters:
i) Plant with variable select Option u2013 Optional.
ii) Calendar Year / Month with Select Option u2013 Optional.
iii) Material with excluded Unassigned (#).
iv) Vendor with excluded Unassigned (#).
Following are we have used for Performance:
i) Aggregates using Propose from query (only for this query).
ii) Partitioning on Calendar Year / Month (For 1 year 14 partitions) i.e. (04.2007 to 03.2008).
iii) Collapse.
iv) In RSRT we have set the following properties
Read Mode = H
Req.Status = 0
Catch Mode = 4
Persistence Mode = 3 (BLOB)
Optimization mode = 0.
Our inputs to this Query:
i) We are passing plant range 1201 to 1299.
ii) Calendar Year / Month 04.2007 to 03.2008.
So please suggest me how to reduce the execution time.
please help me.
Thanks,
kiran manyamHi,
First of all its a complete question with all the details. Good work.
As you partitioned the cube based on calmonth and you are also giving calmonth in selection, it will definitely work towards improved query performance.
As you are putting plant values in the selection, is there any aggregate available on plant characteristics? If not creating a aggregate on plant will help.
Regards,

how to reduce a PDF file size under Adobe Acrobat Reader DC. The size is now 23MB; I need it to be less than 4MB. thanks
I've found in Pdf's many time when you go to Optimize a PDF and look at the font list there are often up to a 1/2dozen copies of a given font, say Helvetica, then that many Helvetica Bold, or Arial or Ariel Italic
What I do ie remove from list all but one copy of each different font. often dramatically reduces the size. also something lese is Flattening images will in some cases reduce a file size. I have run into a case where it actually made a PDF Larger. -
Buying a new Macbook Pro for music recording, should I upgrade the RAM or Processor?
As the title states, I'm looking into buying a new Macbook (15 inch) for music recording. Should I upgrade the processor or the RAM memory?
Purchase it with the faster CPU. RAM may be increased later via third party chips at much lower cost if and when required.

How long will the MBP honestly last?
im endin my senior year of hs and ill need this computer to last me thru 4 yrs of college. is that a realistic expectation of the MBP or am i just kiddin myself?
You're not kidding yourself. But it's hard to answer this absolutely, without knowing what your requirements are. If you'll use the machine for email, web, office apps, etc., I'd say it will definitely last for 4 years, no problem. But if you want always be able to run the latest and greatest 3D-intensive video games on it, I'd say it definitely won't last 4 years. It's very likely at the end of 4 years there will be video games out there that you won't be able to run on a maxed out first-gen MacBook. But then, no computer I know of will keep up with game developers for 4 years.
Do you plan to do heavy graphics (video/imagery) work in college, or CAD, or audio recording/mixing? In these cases, some of the tools you'll use may release new versions that push the envelope for a MacBook near the end of the 4 years. But even in these cases, I think the MacBook will suffice. Worst case scenario, these apps will work, but slower than you'd like, near the end of the 4 years. -
My Macbook Pro is using 320GB on "Backups" and Time Machine is using 640GB. It just seems ridiculous, considering I everything else only takes up 77GB combined. How to I get rid of a good chunk of it from Macbook HD and also how can I reduce the Time Machine parameters, maybe so it starts deleting back up data sooner?
If you run TM you don't really need local snapshots so if you need the disk space you can disable them in Terminal by copying & p;asting this command at the prompt
sudo tmutil disablelocal
Press return. You will be prompted for your password, it will be invisible.
To undo this, rerun it with "enablelocal" instead of "disablelocal".
In TM preferences you can choose to exclude items to the backup.
EDIT: See these helpful hints from Pondini. -
How to reduce Notification popup display time?
I have Notifiation center set to show banners. When I get a notification, an alert (pop up) appears in the upper right of the screen. The alert hangs around for a while. Seems like every time one of these displays, I need access to the area it is covering. But I have to wait for the popup to hide.
Is there a way to reduce the time that these alerts are visible?
Also, is it possible to have notifications cleared out after x number of days?Hi 4thSpace,
The information below explains all of the available options for Notifications.
Mac Basics: Notification Center
You have the option of reducing the number of notifications you receive to 5 or 1.
You can't control how long the notification is on your screen, but you do have the ability to dismiss it:
Tip: To dismiss an Alert or Banner without interacting with it, place the cursor over the banner and use a two finger swipe to the right.
I hope this information helps ...

How to reduce my query execution time?
Hi Friends,
One of my client asked me this question. " My query is taking long time to execute.So how do you reduce this time?" . I replied him saying some performance issues like creating aggregates( offcourse we have to balance the maintenance of it ), creating secondary indexe and cube copression and if possible Cube Partition etc.... I even explained query performance isuues like if possible use RRI, and minimise variables etc....
Can anybody tell me any other factors we can advise?..Anyway it depends on query too.
Thanks

How to reduce this query execution time !
Just use your original cursor as an inline view, like so:
CREATE OR REPLACE PROCEDURE SP_TEST_audit_history2
(p_start IN date,
p_end IN date,
p_msgcode IN varchar2,
p_partnername IN varchar2,
p_status IN varchar2,
p_locationname IN varchar2,
p_custbusunit IN varchar2,
p_sysaudithistory_cur OUT plutotypes.ref_cursor,
p_status1 OUT NUMBER)
AS
BEGIN
OPEN p_sysaudithistory_cur
FOR
SELECT tfm.hubmsgid,
tfm.status || '-'|| nvl2 (tfm.exception_id, 'FAILED', 'OK'),
tfm.datetime,
tfm.exception_id
FROM tfm_status tfm,
(SELECT DISTINCT MAX (tfm.datetime) datetime, tfm.hubmsgid
FROM tfm_status tfm, vw_msgcode_part_locn vw
WHERE tfm.datetime >= NVL (p_start, TO_DATE ('01/01/1981', 'DD/MM/YYYY'))
AND tfm.datetime <= NVL (p_end, TO_DATE ('31/12/9999','DD/MM/YYYY'))
AND tfm.msgcode LIKE NVL (p_msgcode, '%')
AND vw.msgcode = tfm.msgcode
AND vw.partnername LIKE NVL (p_partnername, '%')
AND tfm.status LIKE NVL (p_status, '%')
AND vw.locationname LIKE NVL (p_locationname, '%')
AND vw.custbusunit LIKE NVL (p_custbusunit, '%')
AND rownum < 250
GROUP BY tfm.hubmsgid) c_hubmsgids
WHERE tfm.hubmsgid = c_hubmsgids.hubmsgid /* here only i am getting error*/
AND tfm.datetime = c_hubmsgids.datetime
AND tfm.status like NVL (p_status, '%');
p_status1 := 0;
EXCEPTION
WHEN NO_DATA_FOUND THEN p_status1 := 1;
END SP_TEST_audit_history2;
If i run this query it is taking 18 seconds to retrive the records becoz of that group by clause..
Can any body suggest any changed in code ( any hints) to make it faster that is execution time will be less than 10 seconds
Thanx in advance
prasanth a.s.Try removing the word distinct and see if that helps. Distinct should not be needed since the max and group by will result in distinct values.
