Macbook air updates taking too long

I just bought my macbook air. It needs 13 program updates. I started to do them all at once, and it was estimated to take over 900 hours. I stopped it and started to do them one at a time. Doing that, I was able to update 6 of them. One of them is 66KB and is estimated to take 10 hours. Seems pretty crazy. Is this normal?

Don't get too anxious about estimated times. The estimator constantly updates as the download progresses. It observes how much data needs to be downloaded, how long it took for the portion already downloaded, and extrapolates from that. It gets more accurate as it goes. The numbers can be pretty wild at first. It's like trying to estimate your MPG after driving 2 blocks.

UPDATE taking too long

Hi everyone,
I have a small problem with a simple update statement that takes more than 15 minutes to execute. I really don't understand why it's taking that much. I'm using Oracle 10g (release 5).
Here is the statement:
EXPLAIN PLAN FOR
     UPDATE local_persons a
        SET a.is_deleted = '1'
      WHERE NOT EXISTS (SELECT 1
                          FROM remote_persons_mv z
                         WHERE a.person_id = z.person_id
                           AND a.institution_code = z.institution_code
                         UNION ALL
                        SELECT 1
                          FROM cf_additional_persons z
                         WHERE a.person_id = z.person_id
                           AND z.transform_type = 'CREATE');If you want to know how much records by table (remote_persons_mv is a materialized view).
- local_persons : 48770 records
- cf_additional_person: 4 records
- remote_persons_mv: 48766 records
Here is the execution plan I get.

WHERE table_name = 'LOCAL_PERSONS';
LOCAL_PERSONS     10     48770     622     74     09/11/11
SELECT table_name, pct_free, num_rows, blocks, avg_row_len, last_analyzed

WHERE table_name = 'REMOTE_PERSONS_MV';
REMOTE_PERSONS_MV     10     48766     896     114     09/11/11I know that pct_free is not computed in statistics.
Does anyone have any idea about why is it taking soooo long??
Thanks,

You could also try to change the query so that instead of a NOT exists you do an IN + left join.
Looking at the execution plan the optimizer already seem to be doing this, but I might be mistaken. I just wonder where the second table access to local_persons is coming from.
Also important might be how many rows are already marked as deleted. Your select each time reconsiders those rows, without any need to do so. This might take much time. I added "a.is_deleted = '0' " in the next example.
untested
UPDATE local_persons a
SET a.is_deleted = '1'
WHERE a.is_deleted = '0' /* might be IS NOT NULL expression, depending how your column is filled */
AND a.id in ( /* here we build a list of IDs to be deleted */
select p2.id
from local_persons p2
left join remote_persons_mv z on p2.person_id = z.person_id and p2.institution_code = z.institution_code
left join cf_additional_persons ap on ap.person_id = p2.person_id and ap.transform_type = 'CREATE'
where z.person_id is null
and ap.person_id is null

My macbook pro is taking too long to load

I recently droped my macbook and had to have the hard drive replace. I just got it back, but its taking much longer to load. There is now a light blue screen first, then it swithches to another blue screen with an apple symbol with that thinking circle thing, followed by a darker blue screen with an arrow in top right corner. Then it finally loades. What is Wrong with my macbook?

Check the Startup Disk in System Preferences and make sure your HDD is selected.
Does this happen everytime you re-boot?

Software update taking too long!

Hi,
I recently got myself a Macbook Pro 13" newer version (late 2011 model) running Mac OS X Lion.
Today I got a system update notification for safari, and it asked me to restart the Macbook for system update.
Its been 15 minutes since that update is installing, and after reboot the Macbook is just stuck on "installing 1 item - Running package scripts" in Software Update window.
Mouse is working fine though. Nothing seems frozen - even the progress bar is showing some animation, but it just isnt going ahead!
Any ideas for a Mac noobie?
Much Thanks!

Those CD's that come with the BT HomeHub are a waste of time, they are full of rubbish that you dont need and waste space on the pc. My Hub has been running happily since day one without the software- the settings are changed here http://bthomehub.home the passwords etc are on the back of the Hub and wireless settings card.
If you have Option 2 or 3 Broadband then BT Net Protect is not on the CD, but here:- https://www.securedownload.bt.com/BTGuard/Guard?beanName=OnlineCustomer&block=online&authenticationR...
To get the hub going then you need a pin, push the reset to defaults on the side for about 10 seconds and release, wait for the Hub to boot then it will work as normal.
If your connecting wirelessly then you need the wireless settings card this will tell you what your SSID name is and your passcode- open the wireless networks on your laptop and select device enter passcode- Done!
Hope this helps!

BIOS Update taking too long

I come across that the tablet/pc needes a BIOS Update which automatically began. But that was at 6pm(Puerto Rico Time) and its 10:43pm and its still going. I can not do anything else on the tablet/pc. I bought the tablet/pc online. I got it at the begining of the year. What can I do ?

May I know the model name and number of your device? Also if you can remember the SP number of the BIOS update you used.

HT4736 Taking too long (2 minutes) to locate and download photos into Photo '11 9.5 (902.7 build running on an older Intel based MacBook Pro with iPhoto libraries on a USB2 External HD). I checked and repaired HD permissions. Any ideas?

Regarding iPhoto '11 9.5 (902.7 build running on an older Intel based MacBook Pro with iPhoto libraries on a USB2 External HD). I am dealing with iPhoto taking too long to download photos. Specifically, I rechecked and repaired HD permissions. I am running the most current software my five year old Intel MacBook Pro can run. What happens is that when I connect an external SD card, or my iPhone, the new version of iPhoto takes up to two full minutes to fully acknowledge the device. Then locate new photos and be ready to download them to my external HD. I am kind of concerned about this. This has never happened before.
I take 20,000 photos a year. I really don't want to lose any. Or is there something I am doing wrong? Or need to be aware of? Any experienced suggestions would be appreciated. Thanks. Have a great day.
PS.... The cameras I use are Canon SX-30, Nikon D3100, and my iPhone 4S. Thanks again for your assistance.

Hello Old Toad.... Those sound like great ideas.
I thought I checked and repaired disk permissions on my main boot HD. That boot disk is Mac OS Extended (Journaled) Capacity 749.3 GB. Available 562.53 GB. BUT.... now that I think of it.... the Seagate external HD with USB2 interface is: Mac OS Extended (Journaled), Capacity 639.79 GB, Available 36.2 GB with my latest iPhoto Library 517.37 GB that was already scanned & updated to be read by the latest iPhoto version.
I'll try your suggestions tonight as far as double checking 'permissions' and setting up a tiny test library.
Or maybe it's time to fill up another External HD?
I appreciate your and anyone else's suggestions to try.
Have a great day. ~~ David in Rochester NY

Thank you all for the great ideas, you have been extremely helpful. Here is what we did and were able to resolve the query.
We started with Etbin's idea to create a table from the ext table so that we can index and reference easier than an external table, so we did the following:
SQL> create table ext_person as select P_ID,ED_ID,trim(F_NAME) fst_name,trim(L_NAME) lst_name from EXT_NAMES_CSV;
Table created.
SQL> desc ext_person
Name                                                                                Null?    Type
P_ID                                                                                         NUMBER
ED_ID                                                                                        NUMBER

LST_NAME                                                                                     VARCHAR2(300)

I am trying to update my ipad mini but taking too long time 5 hours

You can try resetting your iPad by simultaneously pressing and holding the Home and Sleep/Wake buttons until you see the Apple Logo. This can take up to 15 seconds so be patient and don't release the buttons until the logo appears.
Try again to see if the problem persists.

Macbook taking too long o start

why is my macbook pro taking too long (interminable) to start, and is still showing the gray screen with the apple logo?

Hi gersedd!
I have an article for you here that seems to describe your issue and can provide you with some troubleshooting steps for this issue:

My iPod was updating to iOS 6 and i shut it off during the update because it was taking too long and now my screen in baby blue i've tried to drain the battery but when i plugged it in to charge the blue screen came back on.I dont know what to do

Try:
- iOS: Not responding or does not turn on
- If not successful and you can't fully turn the iPod fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Update statement taking too long to execute

Hi All,
I'm trying to run this update statement. But its taking too long to execute.
    UPDATE ops_forecast_extract b SET position_id = (SELECT a.row_id
        FROM s_postn a
        WHERE UPPER(a.desc_text) = UPPER(TRIM(B.POSITION_NAME)))
        WHERE position_level = 7
        AND b.am_id IS NULL;
        SELECT COUNT(*) FROM S_POSTN;
        214665
        SELECT COUNT(*) FROM ops_forecast_extract;
        49366
SELECT count(*)
        FROM s_postn a, ops_forecast_extract b
        WHERE UPPER(a.desc_text) = UPPER(TRIM(B.POSITION_NAME));
575What could be the reason for update statement to execute so long?
Thanks

What could be the reason for update statement to execute so long?You haven't said what "too long" means, but a simple reason could be that the scalar subquery on "s_postn" is using a full table scan for each execution. Potentially this subquery gets executed for each row of the "ops_forecast_extract" table that satisfies your filter predicates. "Potentially" because of the cunning "filter/subquery optimization" of the Oracle runtime engine that attempts to cache the results of already executed instances of the subquery. Since the in-memory hash table that holds these cached results is of limited size, the optimization algorithm depends on the sort order of the data and could suffer from hash collisions it's unpredictable how well this optimization works in your particular case.
You might want to check the execution plan, it should tell you at least how Oracle is going to execute the scalar subquery (it doesn't tell you anything about this "filter/subquery optimization" feature).
Generic instructions how to generate a useful explain plan output and how to post it here follow:
Could you please post an properly formatted explain plan output using DBMS_XPLAN.DISPLAY including the "Predicate Information" section below the plan to provide more details regarding your statement. Please use the {noformat}[{noformat}code{noformat}]{noformat} tag before and {noformat}[{noformat}/code{noformat}]{noformat} tag after or the {noformat}{{noformat}code{noformat}}{noformat} tag before and after to enhance readability of the output provided:
In SQL*Plus:
SET LINESIZE 130
EXPLAIN PLAN FOR <your statement>;
SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY);Note that the package DBMS_XPLAN.DISPLAY is only available from 9i on.
In 9i and above, if the "Predicate Information" section is missing from the DBMS_XPLAN.DISPLAY output but you get instead the message "Plan table is old version" then you need to re-create your plan table using the server side script "$ORACLE_HOME/rdbms/admin/utlxplan.sql".
In previous versions you could run the following in SQL*Plus (on the server) instead:
@?/rdbms/admin/utlxplsA different approach in SQL*Plus:
SET AUTOTRACE ON EXPLAIN
<run your statement>;will also show the execution plan.
In order to get a better understanding where your statement spends the time you might want to turn on SQL trace as described here:
When your query takes too long ...
and post the "tkprof" output here, too.

My macbook is taking too long to turn on

my macbook is taking too long to turn on.

Try doing a NVRAM/PRAM reset - after you have done this - go to system preferences - startup disk and select your hard drive as the startup drive and restart your Macbook again.
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
After resetting NVRAM or PRAM, you may need to reconfigure your settings for speaker volume, screen resolution, startup disk selection, and time zone information.

My iPad is taking too long to contact update software server during recovery.

My iPad is taking too long to contact update software server during recovery. It can go on for 30 minutes and it would not load. What can I do?

If the links are blocked by who-ever, you will keep getting those errors.
About the only option would be to use a proxy.
